ADS1220IPWR ADS1220 ADC 24-bit
The ADS1220IPWR from Texas Instruments is a highly integrated, low-power, 24-bit delta-sigma analog-to-digital converter (ADC) specifically engineered for precision measurement of small sensor signals. Operating from a single 2.3V to 5.5V supply, this device features a flexible input multiplexer supporting two differential or four single-ended inputs, a low-noise programmable gain amplifier (PGA) with gains from 1 to 128, and a maximum data rate of 2 kSPS. Its delta-sigma architecture combined with a programmable digital filter provides outstanding noise rejection, achieving an effective resolution of up to 20 bits and offering simultaneous 50Hz/60Hz rejection at 20 SPS.
A key differentiator of the ADS1220IPWR is its comprehensive suite of integrated features designed to minimize external component count and simplify system design. The device includes a 2.048V internal reference with a low drift of 5 ppm/°C, two matched programmable excitation current sources (IDACs) ranging from 10µA to 1.5mA for sensor excitation and RTD lead resistance cancellation, a precision internal temperature sensor accurate to ±0.5°C, and a low-side switch for sensor diagnostics. The SPI-compatible interface supports daisy-chaining of multiple devices and includes a dedicated data-ready (DRDY) pin for efficient data transfer. With a typical current consumption of just 350µA in normal mode and the ability to enter a power-down mode drawing only 50nA, it delivers exceptional performance-per-watt for portable and industrial sensor interfaces.
Alternative Analog-to-Digital Converter Models
1. AD7796 (Analog Devices): A 16/24-bit low-noise ADC with an integrated PGA and reference, optimized for bridge sensors with lower power consumption but fewer integrated features like IDACs.
2. MAX11270 (Maxim Integrated): A 24-bit delta-sigma ADC offering 64 kSPS data rates and a high-impedance PGA, targeting high-speed data acquisition with a smaller 10-pin package footprint.
3. LTC2499 (Analog Devices): A 24-bit high-accuracy delta-sigma ADC with an integrated temperature sensor and Easy Drive technology that cancels differential input current, ideal for direct thermocouple and bridge measurements.
4. CS5532 (Cirrus Logic): A 24-bit delta-sigma ADC with a flexible serial interface and on-chip calibration, commonly used in weigh scale and industrial control applications requiring high resolution.
