PRODUCT OVERVIEW

What Is the ADS1294IPAG?

ADS1294IPAG is a multichannel, simultaneous-sampling, 24-bit, delta-sigma (ΔΣ) analog-to-digital converter (ADC) from Texas Instruments with built-in programmable gain amplifiers (PGAs), internal reference, and an onboard oscillator. The device features 4 differential simultaneous-sampling inputs and offers high performance with low power consumption of 0.75 mW per channel.[reference:0]

The ADS1294IPAG is part of the ADS129x family of multichannel, simultaneous-sampling, 24-bit delta-sigma ADCs designed for medical instrumentation applications including electrocardiogram (ECG), electroencephalogram (EEG), and patient monitoring systems.[reference:1] With high levels of integration and exceptional performance, the device enables the development of scalable medical instrumentation systems at significantly reduced size, power, and overall cost.[reference:2]

The device incorporates all features commonly required in medical biopotential measurement applications including flexible input multiplexers per channel that can be independently connected to internally-generated signals for test, temperature, and lead-off detection.[reference:3] Additionally, the built-in right leg drive (RLD) amplifier, lead-off detection, Wilson central terminal (WCT), and pace detection capabilities make this device ideal for 12-lead ECG and other medical diagnostic applications.[reference:4]

4-Channel Simultaneous Sampling 4 differential inputs with simultaneous sampling for accurate multi-channel biopotential measurements.

Low Power 0.75 mW per channel power consumption with 4 µVPP input-referred noise at 150 Hz BW, G = 6.[reference:5]

Medical-Grade Integration Built-in RLD amplifier, lead-off detection, Wilson central terminal, and pace detection capability.[reference:6]

Circuit Considerations for ADS1294IPAG

Configuration & Interface

The ADS1294IPAG is configured via an SPI-compatible serial interface:

Data Rates: Programmable from 250 SPS to 32 kSPS[reference:12]
PGA Gain: Selectable gain settings: 1, 2, 3, 4, 6, 8, 12[reference:13]
Internal Reference: Integrated reference and onboard oscillator[reference:14]
Lead-Off Detection: Internal pullup/pulldown resistors or excitation current sink/source[reference:15]
RLD Amplifier: Built-in right leg drive amplifier for common-mode rejection[reference:16]
Wilson Central Terminal (WCT): Three integrated amplifiers generate WCT and GCT for standard 12-lead ECG[reference:17]

PCB and Power-Supply Guidance

ADC performance depends on layout, bypassing, and power supply design:

Decouple each AVDD pin to AVSS with a 1-µF capacitor
Connect 1-µF capacitor from VCAP2 to AVSS and 22-µF capacitor from VCAP1 to AVSS
Use unipolar (2.7 V to 5.25 V) or bipolar (±2.5 V) analog supplies[reference:18]
Connect any unused analog input pins to AVDD
Multiple ADS129x devices can be cascaded in daisy-chain configuration[reference:19]
Verify the recommended PCB footprint from the official datasheet before production
