Data sheet:
Application brief:
The ADS981x is an 8-channel data acquisition (DAQ) system based on a dual, simultaneous-sampling, 18-bit successive approximation register (SAR) analog-to-digital converter (ADC). The ADS981x features a complete analog front-end for each channel with an input clamp protection circuit, 1MΩ input impedance, and a programmable gain amplifier (PGA) with user-selectable bandwidth options. The high input impedance allows direct connection with sensors and transformers, thus eliminating the need for external driver circuits. The ADS981x can be configured to accept unipolar or bipolar inputs with up to a ±12V common-mode voltage.
The device also features a 4.096V reference for the ADC and a 2.5V reference output for use with external circuits. A digital interface supporting 1.2V to 1.8V operation enables the ADS981x to be used without external voltage level translators.
- 8-channel, 18-bit ADC with analog front-end:
- Dual, simultaneous sampling: 4 × 1 channels
- Constant 1MΩ input impedance front-end
- Programmable analog input ranges:
- ±12V, ±10V, ±7V, ±5V, ±3.5V, and ±2.5V
- Single-ended and differential inputs
- ±12V common-mode voltage range
- Input overvoltage protection: Up to ±18V
- User-selectable analog input bandwidth:
- 21kHz and 400kHz
- Integrated low-drift precision references
- ADC reference: 4.096V
- 2.5V reference output for external circuits
- Excellent AC and DC performance at full-throughput:
- DNL: ±0.5LSB, INL: ±0.8LSB
- SNR: 92dB, THD: –113dB
- Power supply:
- Analog and digital: 5V and 1.8V
- Digital interface: 1.2V to 1.8V
- Temperature range: –40°C to +125°C
