1.6 V, Micropower 12-/10-/8-Bit ADCs AD7466/AD7467/AD7468 FEATURES FUNCTIONAL BLOCK DIAGRAM Specified for V VDD DD of 1.6 V to 3.6 V Low power: 0.62 mW typical at 100 kSPS with 3 V supplies 12-/10-/8-BIT 0.48 mW typical at 50 kSPS with 3.6 V supplies SUCCESSIVE VIN T/H APPROXIMATION 0.12 mW typical at 100 kSPS with 1.6 V supplies ADC Fast throughput rate: 200 kSPS Wide input bandwidth: 71 dB SNR at 30 kHz input frequency SCLK CONTROL Flexible power/serial clock speed management SDATA LOGIC No pipeline delays CS High speed serial interface: AD7466/AD7467/AD7468 SPI/QSPITM/MICROWIRETM/DSP compatible Automatic power-down GND 02643-001 Power-down mode: 8 nA typical Figure 1. 6-lead SOT-23 package 8-lead MSOP package APPLICATIONS Battery-powered systems Medical instruments Remote data acquisition Isolated data acquisition GENERAL DESCRIPTION PRODUCT HIGHLIGHTS The AD7466/AD7467/AD74681 are 12-/10-/8-bit, high speed, 1. Specified for supply voltages of 1.6 V to 3.6 V. low power, successive approximation analog-to-digital 2. 12-, 10-, and 8-bit ADCs in SOT-23 and MSOP packages. converters (ADCs), respectively. The parts operate from a single 1.6 V to 3.6 V power supply and feature throughput rates up to 3. High throughput rate with low power consumption. 200 kSPS with low power dissipation. The parts contain a low Power consumption in normal mode of operation at noise, wide bandwidth track-and-hold amplifier, which can 100 kSPS and 3 V is 0.9 mW maximum. handle input frequencies in excess of 3 MHz. 4. Flexible power/serial clock speed management. The conversion process and data acquisition are controlled The conversion rate is determined by the serial clock, allowing the conversion time to be reduced through using CS and the serial clock, allowing the devices to interface
