TLV2242IDGKR

The TLV2242IDGKR is a low-power, precision, 18-bit, delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It is designed for use in a variety of applications, including industrial, medical, and consumer electronics.

Description:

The TLV2242IDGKR is a monolithic, 18-bit, successive approximation register (SAR) ADC with a built-in track-and-hold (T&H) amplifier. It operates from a single 2.7V to 5.5V supply and has a low power consumption of typically 130µA at a 50kHz sample rate. The device features a serial interface that is compatible with both SPI and I2C communication protocols.
