ADS1294R Datasheet PDF - TI

●DESCRIPTION

●The ADS1194/6/8 are a family of multichannel, simultaneous sampling, 16-bit, delta-sigma (ΔΣ) analog-to-digital converters (ADCs) with a built-in programmable gain amplifier (PGA), internal reference, and an onboard oscillator.

●With its high levels of integration and exceptional performance, the ADS1194/6/8 family enables the creation of scalable medical instrumentation systems at significantly reduced size, power, and overall cost.
