TPS40428 EVM Dual Output with PMBus Interface

The ADPD6000 is a highly integrated analog front end (AFE) designed for measuring various vital signals.The optical channel is designed as an optical transceiver, stimulating up to four light emitting diodes (LEDs) and measuring the return signal on up to four separate current inputs. The signal chain rejects signal offsets and corruption from asynchronous modulated interference, typically from ambient light, eliminating the need for optical filters or externally controlled dc cancellation circuitry.The electrocardiography (ECG) signal acquisition is designed to support low noise, diagnostic level measurement in the presence of a variety of interferers. The ECG signal chain has a number of complementary features supporting ECG measurement, such as driven reference for common-mode rejection and lead off detection to identify a fallen electrode.The body impedance analysis (BIA) signal chain is designed for body impedance measurement with a configurable excitation path and measurement path. A 12-bit digital-to-analog (DAC) is used in the excitation path to generate the sinusoid wave and high precision measurement, with configurable filters used to measure the body response of the stimulus.The data output and functional configuration use a serial port interface (SPI) on the ADPD6000. The control circuitry includes flexible LED signaling and synchronous detection, digital filters, digital wave generators, and configurable filters.The ADPD6000 is available in a 2.6 mm ? 2.6 mm, 0.4 mm pitch, 36-ball wafer level chip scale package (WLCSP).APPLICATIONS Wearable health and fitness monitors: heart rate, heart rate variability, SpO2, body impedance analysis, hydration, cuffless noninvasive blood pressure Home patient monitoring Industrial monitoring: particle and aerosol, gas, and conductivity detection

The AD9213 is a single, 12-bit, 6 GSPS/10.25 GSPS, radio frequency (RF) analog-to-digital converter (ADC) with a 6.5 GHz input bandwidth. The AD9213 supports high dynamic range frequency and time domain applications requiring wide instantaneous bandwidth and low conversion error rates (CER). The AD9213 features a 16-lane JESD204B interface to support maximum bandwidth capability.The AD9213 achieves dynamic range and linearity performance while consuming <4.6 W typical. The device is based on an interleaved pipeline architecture and features a proprietary calibration and randomization technique that suppresses interleaving spurious artifacts into its noise floor. The linearity performance of the AD9213 is preserved by a combination of on-chip dithering and calibration, which results in excellent spurious-free performance over a wide range of input signal conditions.?Applications that require less instantaneous bandwidth can benefit from the on-chip, digital signal processing (DSP) capability of the AD9213 that reduces the output data rate along with the number of JESD204B lanes required to support the device. The DSP path includes a digital downconverter (DDC) with a 48-bit, numerically controlled oscillator (NCO), followed by an I/Q digital decimator stage that allows selectable decimation rates that are factors of two or three. For fast frequency hopping applications, the AD9213 NCO supports up to 16 profile settings with a separate trigger input, allowing wide surveillance frequency coverage at a reduced JESD204B lane count.The AD9213 supports sample accurate multichip synchronization that includes synchronization of the NCOs. The AD9213 is offered in a 192-ball ball grid array (BGA) package and is specified over a junction temperature range of ?20?C to +115?C.

The ADP1870?/ ADP1871 are versatile current-mode, synchronous step-down controllers that provide superior transient response, optimal stability, and current-limit protection by using a constant on-time, pseudo-fixed frequency with a programmable current-limit, current-control scheme. In addition, these devices offer optimum performance at low duty cycles by utilizing valley current-mode control architecture. This allows the ADP1870 / ADP1871 to drive all N-channel power stages to regulate output voltages as low as 0.6 V.The ADP1871 is the power saving mode (PSM) version of the device and is capable of pulse skipping to maintain output regulation while achieving improved system efficiency at light loads (see the Power Saving Mode (PSM) Version (ADP1871) section for more information).Available in three frequency options (300 kHz, 600 kHz, and 1.0 MHz, plus the PSM option), the ADP1870 / ADP1871 are well suited for a wide range of applications that require a single-input power supply range from 2.95 V to 20 V. Low voltage biasing is supplied via a 5 V internal LDO.In addition, an internally fixed soft start period is included to limit input in-rush current from the input supply during startup and to provide reverse current protection during soft start for a precharged output. The low-side current-sense, current-gain scheme and integration of a boost diode, along with the PSM/forced pulse-width modulation (PWM) option, reduce the external part count and improve efficiency.The ADP1870/ADP1871 operate over the -40?C to +125?C junction temperature range and are available in 10-lead MSOP package.APPLICATIONS Telecom and networking systems Mid to high end servers Set-top boxes DSP core power supplies 12 V input POL supplies
