Analog To Digital Converters (ADC) datasheet and documents for LTC1277ISW#TRPBF

LTC1277ISW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1277ISW#TRPBF is a 12-bit, 100ksps successive approximation analog-to-digital converter (ADC) in a 24-lead SOIC package. It features differential inputs and an internal 2.42V reference. The device operates from a single 5V supply or ±5V supplies, consuming 10mW at full speed. Key power management includes Nap mode (180µA) and Sleep mode (1µA). It supports unipolar (0V to 4.096V) and bipolar (±2.048V) input ranges with offset binary formatting for bipolar operation.

Analog To Digital Converters (ADC) Feature Summary

12-bit resolution with 100ksps sampling rate
Differential analog inputs with internal synchronized clock
Two low-power modes: Nap (180µA) and Sleep (1µA)
Internal 2.42V reference with overdrive capability

Analog To Digital Converters (ADC) Applications

Battery-powered portable systems
High-speed data acquisition for PCs
Multiplexed data acquisition systems
Audio and telecom processing
Spectrum analysis

Analog To Digital Converters (ADC) Procurement Notes

Verify the ISW suffix indicates industrial temperature range (-40°C to 85°C) and SW denotes the 24-lead plastic SO wide package. Confirm TRPBF specifies tape-and-reel packaging with lead-free finish. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when differential input noise immunity is required compared to the single-ended LTC1274. Ensure the system can accommodate the 2-byte read format and HBEN control signal. Verify that the logic supply (VLOGIC) matches the processor voltage if using 3V logic interface options.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1274/LTC1277 family of low-power, high-speed ADCs. The LTC1277 variant specifically provides differential inputs and a two-byte data output structure, distinguishing it from the single-ended LTC1274. Both share identical power consumption profiles and internal reference characteristics.
