The ADS1217IPFBR is a precision 24-bit, 8-channel multiplexed delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It combines a high-resolution converter with a programmable gain amplifier (PGA) that supports gains from 1 to 128, enabling direct measurement of small sensor signals. The device includes an on-chip 1.25V/2.5V reference, excitation current sources (iDACs), GPIO, and an oscillator, and offers 50/60 Hz rejection for noisy industrial environments. The SPI-compatible digital interface simplifies connection to microcontrollers and digital signal processors.
Key electrical specifications include differential inputs with an input voltage range of 0 V to 5.25 V, an analog and digital supply range of 2.7 V to 5.25 V, and typical power consumption of 0.8 mW at 3 V. The ADC achieves a maximum data output rate of 1 kHz and features single-cycle settling mode, programmable data output rates, and on-chip calibration. Integral non-linearity (INL) is rated at 0.0012% of full-scale range maximum, and effective resolution is 22 bits at PGA=1 and 19 bits at PGA=128.
This ADC is suited for industrial process control, liquid/gas chromatography, blood analysis, smart transmitters, portable instrumentation, weigh scales, pressure transducers, and other precision measurement applications requiring high resolution and low power.
The ADS1217IPFBR is offered in a 48-pin TQFP package (PFB) measuring 9 mm × 9 mm, with surface-mount mounting for compact PCB layouts. It operates over a temperature range of -40°C to 85°C, making it suitable for industrial environments.
