The ADS1299-4PAG is a low-noise, 4-channel, 24-bit simultaneous-sampling delta-sigma analog-to-digital converter (ADC) with a built-in programmable gain amplifier (PGA), internal reference, and onboard oscillator from Texas Instruments. It is designed for biopotential measurements such as electroencephalogram (EEG) and electrocardiography (ECG).
Key electrical specifications include an input-referred noise of 1 µVpp at 70 Hz bandwidth, input bias current of 300 pA, data rate from 250 SPS to 16 kSPS, common-mode rejection ratio of -110 dB, and programmable gain of 1, 2, 4, 6, 8, 12, or 24. The device operates with analog supply voltage from 4.75 V to 5.25 V and digital supply from 1.8 V to 3.6 V. Communication is via an SPI-compatible serial interface.
The ADS1299-4PAG comes in a 64-TQFP (10x10 mm) surface-mount package and operates over a temperature range of -40°C to +85°C. It includes built-in features such as a bias drive amplifier, lead-off detection, test signals, and flexible power-down/standby modes.
