ADS7043
Overview
The ADS7043 is a 1-MSPS, analog-to-digital converter (ADC). The device supports a wide analog input voltage range (±0.825 V to ±1.8 V) and includes a capacitor-based, successive-approximation register (SAR) ADC with an inherent sample-and-hold circuit.
- 1 Industry's First SAR ADC with Nanowatt Power Consumption: - 243 µW at 1 MSPS with 1.8-V AVDD - 780 µW at 1 MSPS with 3-V AVDD - 78 µW at 100 kSPS with 3-V AVDD - Less than 1 µW at 1 kSPS with 3-V AVDD
- Industry's Smallest SAR ADC: - X2QFN-8 Package with 2.25-mm2 Footprint
- 1-MSPS Throughput with Zero Data Latency
- Wide Operating Range: - AVDD: 1.65 V to 3.6 V - DVDD: 1.65 V to 3.6 V (Independent of AVDD) - Temperature Range: -40°C to 125°C
- Excellent Performance: - 12-Bit Resolution with NMC - ±1-LSB (Max) DNL and INL - 70-dB SNR with 3-V AVDD - -80-dB THD with 3-V AVDD
- Unipolar, Pseudo-Differential Input Range: -AVDD / 2 to AVDD / 2
- Integrated Offset Calibration
- SPI™-Compatible Serial Interface: 16 MHz
- JESD8-7A Compliant Digital I/O
