ADS122C04IPWR – TEXAS INSTRUMENTS

The Texas Instruments ADS122C04IPWR is a low-power, 24-bit delta-sigma analog-to-digital converter (ADC) housed in a 16-pin WSON package. It features a single-ended input, capable of measuring voltages within a ±2.5V range, though an external reference voltage allows for adjustments. The device boasts a maximum sampling rate of 20kSPS and achieves a typical input-referred noise density of 2.6nV/√Hz, contributing to high resolution and accuracy in low-signal applications. Its internal oscillator eliminates the need for external clocking, simplifying design._x000D_

The ADS122C04IPWR incorporates features like programmable gain amplification (PGA) with gains of 1, 2, 4, 8, and 16, enabling versatile signal conditioning. Internal filtering options, including a programmable sinc filter, allow for noise reduction tailored to specific application requirements. This ADC is ideal for biomedical instrumentation requiring high resolution and low power consumption, such as ECG, EEG, and other biopotential measurements. Its low noise characteristics and high resolution make it suitable for precision sensor interfacing where subtle signal variations need accurate capture. The single-ended input simplifies circuit design compared to differential input ADCs, reducing component count and PCB space.
