The ADBMS18181 is a multicell battery stack monitor that measures up to 18 series connected battery cells with a total measurement error of less than 3.0 mV. The cell measurement range of 0 V to 5 V makes the ADBMS1818 suitable for most battery chemistries. All 18 cells can be measured in 290 ?s, and lower data acquisition rates can be selected for high noise reduction. Multiple ADBMS1818 devices can be connected in series, permitting simultaneous cell monitoring of long, high voltage battery strings. Each ADBMS1818 has an isoSPI? interface for high speed, RF immune, long distance communications. Multiple devices are connected in a daisy chain with one host processor connection for all devices. This daisy chain can be operated bidirectionally, ensuring communication integrity, even in the event of a fault along the communication path. The ADBMS1818 can be powered directly from the battery stack or from an isolated supply. The ADBMS1818 includes passive balancing for each cell, with individual PWM duty cycle control for each cell. Other features include an on-board 5 V regulator, nine general purpose I/O lines, and a sleep mode, where current consumption is reduced to 6 ?A.

The LTC5507 is an RF power detector for applications operating from 100kHz to 1000MHz. The input frequency range is determined by an external capacitor. A temperature-compensated Schottky diode peak detector and buffer amplifier are combined in a small 6-pin ThinSOT package.The RF input voltage is peak detected using an on-chip Schottky diode and external capacitor. The detected voltage is buffered and supplied to the VOUT pin. A power saving shutdown mode reduces supply current to less than 2?A.Applications Wireless Transceivers Wireless and Cable Infrastructure RF Power Alarm Envelope Detector

Demonstration circuit 2810A features the LTM4673: the wide input and output voltage range, high efficiency and power density, quad output DC/DC step-down μModule® regulator with Digital Interface for control and monitoring. The DC2810A default input voltage range is 4.5V to 15V. However, if VIN is lower than 4.5V, minor modification to certain existing onboard components is required. Please refer to Step 8: Operation at VIN ≤ 4.5V in Quick Start Procedure section. The factory default output voltages are VOUT0 = 1V, VOUT3 = 0.9V at 12A per channel; VOUT1 = 1.2V, VOUT2 = 1.8V at 5A per channel. The DC2810A output voltages can be adjusted from 0.6V up to 3.3V for channel 0 and channel 3 and from 0.6V to 5.5V for channel 1 and channel 2. The default switching frequencies are 600kHz for channel 0 and channel 3 and 1MHz for channel 1 and channel 2. Forced airflow and heatsink might also be used to further optimize the output power when all output rails are on and fully loaded. Programming the output voltages to values greater than 1.8V, may require derating output current based on thermal derating curves provided in the data sheet of the LTM4673. The DC2810A comes with PMBus interface and digital power system management functions. An onboard 12-pin connector is available for users to connect the dongle DC1613A to the DC2810A and provides an easy way to communicate and program the part using LTpowerPlay® software development tool. LTpowerPlay software and I2C/PMBus/SMBus Dongle DC1613A allows users to monitor real time telemetry of input and output voltages, input and output current, internal IC die temperatures, and fault logs. The LTM4673 is available in a thermally enhanced, low profile, 361-Lead (16mm × 16mm × 4.72mm) BGA package. It is recommended to read the data sheet and demo manual of LTM4673 prior to use or making any hardware changes to DC2810A. LTpowerPlay software can be downloaded here. The USB to PMBus Controller Dongle DC1613A for use with LTpowerPlay is available here.

The AD8253 is an instrumentation amplifier with digitally programmable gains that has gigaohm (G?) input impedance, low output noise, and low distortion, making it suitable for interfacing with sensors and driving high sample rate analog-to-digital converters (ADCs).It has a high bandwidth of 10 MHz, low THD of ?110 dB, and fast settling time of 780 ns (maximum) to 0.001%. Offset drift and gain drift are guaranteed to 1.2 ?V/?C and 10 ppm/?C, respectively, for G = 1000. In addition to its wide input common voltage range, it boasts a high common-mode rejection of 100 dB at G = 1000 from dc to 20 kHz. The combination of precision dc performance coupled with high speed capabilities makes the AD8253 an excellent candidate for data acquisition. Furthermore, this monolithic solution simplifies design and manufacturing and boosts performance of instrumentation by maintaining a tight match of internal resistors and amplifiers.The AD8253 user interface consists of a parallel port that allows users to set the gain in one of two different ways (see Figure 1 for the functional block diagram). A 2-bit word sent via a bus can be latched using the WR input. An alternative is to use transparent gain mode, where the state of logic levels at the gain port determines the gain.The AD8253 is available in a 10-lead MSOP package and is specified over the ?40?C to +85?C temperature range, making it an excellent solution for applications where size and packing density are important considerations.ApplicationsData acquisition Biomedical analysis Test and measurement

Demonstration circuit 2290A features the LTC2387 family. With up to 15Msps, these differential input, single channel, 18-/16-Bit, serial, high speed successive approximation register (SAR) ADCs are available in a 32-Pin QFN package. The LTC2387 family has an internal 20ppm/°C reference and a serial LVDS interface. The demo manual refers to the LTC2387 but applies to all members of the family, the only difference being the sample rate and the number of bits. The DC2290A demonstrates the AC performance of the LTC2387 in conjunction with the DC718 data collection board. Differential amplifier demo boards are available separately that provide amplification of low level differential signals if required. Alternatively, by connecting the DC2290A into a customer application the performance of the LTC2387 can be evaluated directly in that circuit.

The LTC1923 is a pulse width modulator intended for thermoelectric cooler (TEC) or heater applications requiring either unidirectional or bidirectional drive circuits. All of the necessary control circuitry and two sets of complementary output drivers are integrated into the LTC1923 to drive a full bridge, providing an efficient means of bidirectional current flow to the TEC. An accurate temperature control loop to stabilize the temperature of a laser diode system is easily achieved with the addition of just a few external components. Typical temperature setpoint accuracy of 0.1?C is achievable with the LTC1923.
