24-Bit Analog-to-Digital Converters for Temperature Sensors

the ads1246 ads1247 and ads1248 are highly-integrated precision 24-bit analog-to-digital converters (adcs). the ads1246/7/8 feature an onboard low-noise programmable gain amplifier (pga) a precision delta-sigma () adc with a single-cycle settling digital filter and an internal oscillator. the ads1247 and ads1248 also provide a built-in very low drift voltage reference with 10ma output capacity and two matched programmable current digital-to-analog converters (dacs). the ads1246/7/8 provide a complete front-end solution for temperature sensor applications including thermal couples thermistors and rtds. an input multiplexer supports four differential inputs for the ads1248 two for the ads1247 and one for the ads1246. view all in datasheet
