a 2.7 V to 5.5 V, 200 kSPS 8-Bit Sampling ADC AD7819 FEATURES FUNCTIONAL BLOCK DIAGRAM 8-Bit ADC with 4.5 s Conversion Time V On-Chip Track and Hold DD AGND VREF Operating Supply Range: 2.7 V to 5.5 VSpecifications at 2.7 V ­ 3.6 V and 5 V 10% AD7819 DB7 CHARGE 8-Bit Parallel Interface REDISTRIBUTION THREE- 8-Bit Read DAC STATE DRIVERS Power Performance CLOCK DB0 Normal Operation OSC 10.5 mW, VDD = 3 V Automatic Power-Down CONTROL COMP T/H LOGIC V 57.75 W @ 1 kSPS, V IN DD = 3 V Analog Input Range: 0 V to VREFReference Input Range: 1.2 V to VDD BUSY CS RD CONVST GENERAL DESCRIPTION PRODUCT HIGHLIGHTS The AD7819 is a high speed, microprocessor-compatible, 8-bit 1. Low Power, Single Supply Operation analog-to-digital converter with a maximum throughput of The AD7819 operates from a single 2.7 V to 5.5 V supply 200 kSPS. The converter operates off a single 2.7 V to 5.5 V and typically consumes only 10.5 mW of power. The power supply and contains a 4.5 µs successive approximation A/D dissipation can be significantly reduced at lower through- converter, track/hold circuitry, on-chip clock oscillator and 8-bit put rates by using the automatic power-down mode. wide parallel interface. The parallel interface is designed to 2. Automatic Power-Down
