LTC1196-1ACS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1196-1ACS8#TRPBF is an 8-bit, 1Msps successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices. It operates on a single 2.7V to 6V supply with power dissipation of 10mW at 3V and 50mW at 5V. The device features a differential analog input, external reference capability, and a 3-wire serial interface (CS, CLK, DOUT). Key electrical specifications include ±1/2 LSB total unadjusted error over temperature, 1V to 5V input span range, and a maximum sampling frequency of 1MHz at 5V. It is housed in an 8-lead plastic SO package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the part marking '11961A' corresponds to the LTC1196-1ACS8#TRPBF variant. Confirm the package is 8-Lead Plastic SO and the operating temperature range is 0°C to 70°C. Ensure the datasheet version matches the specific ordering suffix requirements for lead-free finish.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring a differential input configuration and external voltage reference. The -1 suffix indicates a single-channel differential input, distinguishing it from the -2 suffix which may imply different input configurations. Ensure the system clock can support up to 14.4MHz for maximum conversion speed at 5V operation.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1196/LTC1198 family of high-speed, low-power 8-bit ADCs. The LTC1196 variant specifically provides a differential input architecture, whereas the LTC1198 offers a multiplexed single-ended input with auto-shutdown capabilities. Both share similar performance metrics but differ in input structure and power management features.
