Description
ADS112C04IRTER is TI’s 4-channel, low-power delta-sigma ADC. It provides a programmable input multiplexer (four inputs that can be used as single-ended or two differential channels), a programmable gain amplifier, and options for an internal reference. It uses a serial SPI-like interface, supports multiple data rates, and operates from about 2.7 to 5.25 V with low power consumption. Applications include precision sensing, instrumentation, weigh scales, and battery-powered data logging. The IRTER suffix typically denotes the device’s packaging/tape-and-reel variant; check the TI datasheet for exact package type and temperature range.
