The device supports a wide analog Consumption: input voltage range (1.65 V to 3.6 V) and includes a – 189 µW at 1 MSPS with 1.8-V AVDD capacitor-based, successive-approximation register – 600 µW at 1 MSPS with 3-V AVDD (SAR) ADC with an inherent sample-and-hold circuit. The SPI-compatible serial interface is controlled by – 60 µW at 100 kSPS with 3-V AVDD the CS and SCLK signals. The input signal is – Less than 1 µW at 1 kSPS with 3-V AVDD sampled with the CS falling edge and SCLK is used • Industry's Smallest SAR ADC: for conversion and serial data output. The device supports a wide digital supply range (1.65 V to 3.6 V), – X2QFN-8 Package with 2.25-mm2 Footprint enabling direct interface to a variety of host • 1-MSPS Throughput with Zero Data Latency controllers. The ADS7041 complies with the JESD8- • Wide Operating Range: 7A standard for a normal DVDD range (1.65 V to 1.95 V). – AVDD: 1.65 V to 3.6 V – DVDD: 1.65 V to 3.6 V (Independent of AVDD) The ADS7041 is available in 8-pin, miniature, leaded, and X2QFN packages and is specified for operation – Temperature Range: –40°C to 125°C from –40°C to 125°C. Miniature form-factor and • Excellent Performance: extremely low-power consumption make this device – 10-Bit Resolution with NMC suitable for space-constrained, battery-powered applications. – ±0.8-LSB (Max) INL, ±0.7-LSB (Max) DNL – 61-dB SNR with 3-V AVDD Device Information(1) – –75-dB THD with 3-V AVDD PART NAME PACKAGE BODY SIZE (NOM) • Unipolar Input Range: 0 V to AVDD X2QFN (8) 1.50 mm × 1.50 mm ADS7041 • Integrated Offset Calibration VSSOP (8) 2.30 mm × 2.00 mm • SPI™-Compatible Serial Interface: 14 MHz (1) For all available packages, see the orderable addendum at the end of the datasheet. • JESD8-7A Compliant Digital I/O space 2 Applications space • Low-Power Data Acquisition space • Battery-Powered Handheld Equipment • Level Sensors Typical Application • Ultrasonic Flow Meters • Motor Control • Wearable Fitness • Portable Medical Equipment • Hard Drives • Glucose Meters NOTE: The ADS7041 is smaller than a 0805 (2012 metric) SMD component. 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
