LTC1594LCS#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1594LCS#TRPBF is a micropower, 12-bit successive approximation register (SAR) 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 offers a maximum sampling rate of 10.5ksps with guaranteed ±3/4LSB differential nonlinearity (DNL). It utilizes a serial interface compatible with QSPI, SPI, and MICROWIRE protocols. The component is housed in a 16-lead narrow SOIC package and is rated for commercial operating temperatures from 0°C to +70°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging when sourcing this specific part number. Confirm the LCS suffix corresponds to the commercial temperature range (0°C to +70°C) and the 16-pin SOIC package. Ensure compatibility with 3V logic levels for the serial interface connections.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1594LCS#TRPBF for applications requiring low power consumption on a 3V supply. Choose this model over the 5V versions (LTC1594/LTC1598) if system voltage is limited to 3.6V maximum. Consider the LTC1598L variant if 8 channels are required instead of 4. Ensure the serial interface timing meets the microprocessor's clock requirements for up to 200kHz.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1594L/LTC1598L family of micropower sampling ADCs. The 'L' designation specifically denotes 3V operation, distinguishing it from the standard 5V LTC1594/LTC1598 series. The 'CS' suffix identifies the commercial temperature grade and SOIC package, while '#TRPBF' specifies the reel packaging format.
