LTC1594LIS#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1594LIS#TRPBF is a micropower, 12-bit successive approximation analog-to-digital converter (ADC) featuring a 4-channel multiplexer. It operates on a single 3V supply (2.7V to 3.6V) and typically draws 160μA during conversion, automatically powering down to 1nA between conversions. The device supports a maximum sampling rate of 10.5ksps with a serial interface compatible with QSPI, SPI, and MICROWIRE. It guarantees ±3/4LSB max DNL and no missing codes over the industrial temperature range (-40°C to +85°C). Packaged in a 16-lead narrow SOIC, it includes separate MUX and ADC control for flexible system integration.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the #TRPBF suffix indicates tape and reel packaging, distinct from tube packaging. Confirm the IS suffix corresponds to the -40°C to +85°C industrial temperature grade. Ensure the 16-lead narrow SO package matches the PCB footprint requirements. Check for RoHS compliance status as specified in the manufacturer's documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low power consumption on a 3V supply. The LTC1594L provides 4 channels, whereas the LTC1598L offers 8 channels. For 5V operation, use the non-L variants (LTC1594/LTC1598). Ensure the external reference voltage is within the 1.5V to VCC range. Verify that the serial clock frequency does not exceed 200kHz at elevated temperatures to maintain accuracy.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1594L/LTC1598L family of micropower sampling ADCs. The 'L' designation specifies 3V operation, while 'IS' denotes the industrial temperature range and SOIC package. The '#TRPBF' suffix typically indicates tape and reel packaging with lead-free finish, differing from the tube-packaged equivalents like LTC1594LIS.
