PRODUCTION DATA. ADC081S021 SNAS308G – APRIL 2005 – REVISED MAY 2016 ADC081S021 Single-Channel, 50-ksps to 200-ksps, 8-Bit A/D Converter 1 1 Features 1 • Characterized and Specified Over Multiple Sample Rates • 6-Pin WSON and SOT-23 Packages • Variable Power Management • Single Power Supply With 2.7-V to 5.25-V Range • Compatible With SPI™, QSPI™, MICROWIRE™, and DSP • DNL: +0.04/–0.03 LSB (Typical) • INL: +0.04/–0.03 LSB (Typical) • SNR: 49.6 dB (Typical) • Power Consumption: – 3.6-V Supply: 1.3 mW (Typical) – 5.25-V Supply: 7.7 mW (Typical) 2 Applications • Portable Systems • Remote Data Acquisition • Instrumentation and Control Systems 3 Description The ADC081S021 device is a low-power, single- channel CMOS 8-bit analog-to-digital converter with a high-speed serial interface. Unlike the conventional practice of specifying performance at a single sample rate only, the ADC081S021 is fully specified over a sample rate range of 50 ksps to 200 ksps. The converter is based upon a successive-approximation register architecture with an internal track-and-hold circuit. The output serial data is straight binary, and is compatible with several standards, such as SPI, QSPI, MICROWIRE, and many common DSP serial interfaces. The ADC081S021 operates with a single supply that can range from 2.7 V to 5.25 V. Normal power consumption using a 3.6-V or 5.25-V supply is 1.3 mW and 7.7 mW, respectively. The power-down feature reduces the power consumption to as low as 2.6 µW using a 5.25-V supply. The ADC081S021 is packaged in 6-pin WSON and SOT-23 packages. Operation over the industrial temperature range of −40°C to 85°C is ensured. Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) ADC081S021 SOT-23 (6) 2.50 mm × 2.20 mm WSON (6) 1.60 mm × 2.90 mm (1) For all available packages, see the orderable addendum at the end of the data sheet.
