ADS1292IRSMR Description

Short technical summary and product information.

The ADS1292IRSMR is a multichannel, simultaneous sampling, 24-bit, delta-sigma analog-to-digital converter (ADC) with a built-in programmable gain amplifier (PGA), internal reference, and an onboard oscillator from Texas Instruments. This device is part of the ADS1292 family and is specifically designed for portable, low-power medical electrocardiogram (ECG) applications.

 

Key electrical specifications include a resolution of 24 bits, two input channels, and a low power consumption of 335 µW per channel. The device supports a data rate range from 125 SPS to 8 kSPS and offers a programmable gain of 1, 2, 3, 4, 6, 8, or 12. It features a high CMRR of 120 dB and a low input-referred noise of 8 µVpp (150-Hz BW, G=6). The analog supply voltage range is 2.7V to 5.25V, and the digital supply voltage range is 1.7V to 3.6V.

 

The ADS1292IRSMR is housed in a 32-VFQFN Exposed Pad package (32-VQFN 4x4mm) and is designed for surface mount mounting. It operates over a temperature range of -40°C to +85°C. The device includes features such as a built-in right leg drive amplifier, lead-off detection, and test signals, making it suitable for 3-lead, 5-lead, and 6-lead ECG systems.
