Description
The ADS1191/2 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.
The ADS1191/2 incorporate all of the features that are commonly required in portable, low-power medical electrocardiogram (ECG), sports, and fitness applications.
With its high levels of integration and exceptional performance, the ADS1191/2 family enables the creation of scalable medical instrumentation systems at significantly reduced size, power, and overall cost.
The ADS1191/2 have a flexible input multiplexer per channel that can be independently connected to the internally-generated signals for test, temperature, and lead-off detection. Additionally, any configuration of input channels can be selected for derivation of the right leg drive (RLD) output signal. The ADS1191/2 operate at data rates up to 8 kSPS. Lead-off detection can be implemented internal to the device, using the device internal excitation current sink/source.
The devices are packaged in a 5-mm × 5-mm, 32-pin thin quad flat pack (TQFP). Operating temperature is specified from –40°C to +85°C.
