2.35 V to 5.25 V, 1 MSPS, 12-/10-/8-Bit ADCs in 6-Lead SC70 AD7476A/AD7477A/AD7478A FEATURES FUNCTIONAL BLOCK DIAGRAM Fast throughput rate: 1 MSPS VDD Specified for VDD of 2.35 V to 5.25 V Low power 12-/10-/8-BIT 3.6 mW at 1 MSPS with 3 V supplies SUCCESSIVE- VIN T/H APPROXIMATION 12.5 mW at 1 MSPS with 5 V supplies ADC Wide input bandwidth 71 dB SNR at 100 kHz input frequency Flexible power/serial clock speed management SCLK No pipeline delays CONTROL SDATA LOGIC High speed serial interface CS SPI®/QSPITM/MICROWIRETM/DSP compatible AD7476A/AD7477A/AD7478A Standby mode: 1 A maximum 6-lead SC70 package GND 02930-001 8-lead MSOP package Figure 1. APPLICATIONS Battery-powered systems Personal digital assistants Medical instruments Mobile communications Instrumentation and control systems Data acquisition systems High speed modems Optical sensors GENERAL DESCRIPTION PRODUCT HIGHLIGHTS The AD7476A/AD7477A/AD7478A are 12-bit, 10-bit, and 8-bit 1. First 12-/10-/8-bit ADCs in a SC70 package. high speed, low power, successive-approximation analog-to-digital converters (ADCs), respectively. The parts operate from 2. High throughput with low power consumption. a single 2.35 V to 5.25 V power supply and feature throughput 3. Flexible power/serial clock speed management. The rates up to 1 MSPS. The parts contain a low noise, wide conversion rate is determined by the serial clock, allowing bandwidth track-and-hold amplifier that can handle input the conversion time to be reduced through the serial clock frequencies in excess of 13 MHz. The conversion process and speed increase. This allows the average power consumption data acquisition are controlled using CS and the serial clock, to be reduced when a power-down mode is used while not
