The LTC2486 is a 4-channel (2-channel differential), 16-bit, No Latency ??? ADC with Easy Drive? technology. The patented sampling scheme eliminates dynamic input current errors and the shortcomings of on-chip buffering through automatic cancellation of differential input current. This allows large external source impedances and rail-to-rail input signals to be directly digitized while maintaining exceptional DC accuracy. The LTC2486 includes programmable gain, a high accuracy temperature sensor, and an integrated oscillator. This device can be configured to measure an external signal (from combinations of 4 analog input channels operating in single ended or differential modes) or its internal temperature sensor. It can be programmed to reject line frequencies of 50Hz, 60Hz, or simultaneous 50Hz/60Hz, provide a programmable gain from 1 to 256 in 8 steps, and configured to double its output rate. The integrated temperature sensor offers 1/2?C resolution and 2?C absolute accuracy. The LTC2486 allows a wide common mode input range (0V to VCC), independent of the reference voltage. Any combination of single-ended or differential inputs can be selected and the first conversion after a new channel selection is valid.Applications Direct Sensor Digitizer Direct Temperature Measurement Instrumentation Industrial Process Control

DC1012A-C: Demo Board for the LTC2495 16-Bit 8-/16-Channel ΔΣ ADC with PGA, Easy Drive and I2C Interface

Demonstration circuits 1024A-A and 1024A-B are Micropower Low Noise Boost Converters With Output Disconnect featuring the LT3494 and LT3494A respectively. The demo circuits demonstrate small size and low component count in Boost configuration. Both demo versions are designed to convert a 3V-4.2V source to 15V. The only difference is in the load capability. The 1024A–A supplies 17mA at 3VIN while the 1024A–B supplies 27mA, also at 3VIN. The LT3494 features integrated Schottky diode, output disconnect function, dimming control, output sense resistor and non-audible switching frequency over the entire load range.

The LTC2928 is a four channel cascadable power supply sequencer and high accuracy supervisor. Sequencing thresholds, order and timing are con?gured with just a few external components, negating the need for PC board layout or software changes during system development. Multiple LTC2928s may be easily connected to sequence an unlimited number of power supplies.Sequence outputs control supply enable pins or N-channel pass gates. Precision input comparators with individual outputs monitor power supply voltages to 1.5% accuracy. Supervisory functions include undervoltage and overvoltage monitoring and reporting as well as ?P reset generation. RST may be forced high to complement margin testing.Application faults, whether internally or externally generated, can shutdown all controlled supplies. The type and source of faults are reported for diagnosis. Individual channel controls are available to independently exercise enable outputs and supervisory functions.A high voltage input allows the LTC2928 to be powered from voltages as high as 16.5V. A buffered reference output permits single negative power supply sequencing and monitoring operations.Applications?

The LTC1068 product family consists of four monolithic clock-tunable filter building blocks. Each product contains four matched, low noise, high accuracy 2nd order switched-capacitor filter sections. An external clock tunes the center frequency of each 2nd order filter section. The LTC1068 products differ only in their clock-to-center frequency ratio. The clock-to-center frequency ratio is set to 200:1 (LTC1068-200), 100:1 (LTC1068), 50:1 (LTC1068-50) or 25:1 (LTC1068-25). External resistors can modify the clock-to-center frequency ratio. High performance, quad 2nd order, dual 4th order or 8th order filters can be designed with an LTC1068 family product. Designing filters with an LTC1068 product is fully supported by FilterCAD? filter design software for Windows. The LTC1068 products are available in a 28-pin SSOP surface mount package. A customized version of an LTC1068 family product can be obtained in a 16-lead SO package with internal thin-film resistors.

Demonstration circuit 1055 is a 250mA Universal Nine Channel Multimode (1x, 1.5x, 2x) Charge Pump LED Driver with two RGB displays and three white LEDs featuring the LTC3219. The LTC3219 is a low noise charge pump designed to drive nine universal LED current sources. The input voltage range is 2.9V to 5.5V. Each channel provides 28mA of LED current. The LTC3219 requires only five small ceramic capacitors to form a complete LED power supply and current controller. The maximum display currents are set with an internal precision current reference. On/Off blinking, gradation, and intensity are achieved via an I2C serial interface. There are 64 dimming states available for the universal LEDs. The DC590 controller board is required for proper operation.
