LTC1298IS8#TRPBF

The LTC1298IS8#TRPBF is a 12-bit successive approximation sampling Analog-to-Digital Converter (ADC) from LT, designed for micropower applications. It typically consumes only 250µA during conversion and automatically powers down to 1nA when idle, making it ideal for battery-operated systems.

This ADC offers a 12-bit resolution and a sampling rate of 11.1 kSPS, with a conversion time of 60µs. It operates on a single supply voltage ranging from 5V to 9V and includes an on-chip sample-and-hold circuit. The LTC1298 features a software-selectable 2-channel multiplexer (MUX) and on-chip serial ports compatible with SPI and Microwire interfaces for efficient data transfer.

The device is packaged in an 8-pin SOIC package, suitable for surface mounting. Its high impedance analog inputs and ability to operate with reduced spans allow direct connection to sensors and transducers, eliminating the need for external gain stages in many applications. This makes it suitable for remote data acquisition, battery monitoring, and isolated data acquisition systems.

Key specifications include a typical supply current of 250µA during conversion, auto-shutdown to 1nA, guaranteed ±3/4LSB max DNL, and a conversion time of 60µs. The LTC1298 is designed for applications requiring low power consumption and efficient data conversion.
