ADS7040
Overview
The ADS7040 is a 8-bit, 1-MSPS, analog-to-digital converter (ADC). The device supports a wide analog input voltage range (1.65 V to 3.6 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: - 171 µW at 1 MSPS with 1.8-V AVDD - 555 µW at 1 MSPS with 3-V AVDD - 56 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: - 8-Bit Resolution with NMC - ±0.5-LSB (Max) INL, ±0.4-LSB (Max) DNL - 49 dB SNR - -70-dB THD
- Unipolar Input Range: 0 V to AVDD
- Integrated Offset Calibration
- SPI™-Compatible Serial Interface: 12 MHz
- JESD8-7A Compliant Digital I/O
