LTC1594IS#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1594IS#TRPBF is a micropower, 12-bit successive approximation analog-to-digital converter (ADC) featuring a 4-channel multiplexer. It operates on a single 5V supply with typical supply current of 320μA during conversion and automatically powers down to 1nA between conversions. The device includes a sample-and-hold circuit and serial I/O compatible with QSPI, SPI, and MICROWIRE protocols. Key electrical parameters include a maximum sampling rate of 16.8ksps, guaranteed ±3/4LSB max DNL, and an operating temperature range of –40°C to 85°C.

• 12-bit resolution with 4-channel analog multiplexer
• Micropower consumption: 320μA active, 1nA shutdown
• Single 5V supply operation with ratiometric capability
• Serial interface compatible with standard microprocessor buses

Analog To Digital Converters (ADC) Applications

• Battery-operated systems
• Remote data acquisition
• Isolated data acquisition
• Temperature measurement

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF indicates lead-free tape and reel packaging. Confirm the IS suffix corresponds to the industrial temperature range of –40°C to 85°C. Ensure the specific package type matches the design requirements for the 16-pin narrow SO footprint.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low power consumption in battery-driven environments. The 4-channel MUX allows direct connection to multiple sensors without external switching. Verify that the input signal range fits within the VREF span, as the ADC supports reduced spans down to 1.5V for higher resolution.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1594/LTC1598 family of micropower sampling ADCs. The LTC1594 variant specifically integrates a 4-channel multiplexer, whereas the LTC1598 offers 8 channels. Both share identical core ADC performance but differ in pin count and channel availability.
