Description
Reference Input, 1.2 V to V
Analog Input, 0 V to V
Analog and Digital Ground.
Convert Start. A low-to-high transition on this pin initiates a 1.5 µs pulse on an internally generated
CONVST signal. A high-to-low transition on this line initiates the conversion process if the internal
CONVST signal is low. Depending on the signal on this pin at the end of a conversion, the AD7813
automatically powers down.
Chip Select. This is a logic input. CS is used in conjunction with RD to enable outputs.
Read Pin. This is a logic input. When CS is low and RD goes low, the DB7–DB0 leave their high
impedance state and data is driven onto the data bus.
ADC Busy Signal. This is a logic output. This signal goes logic high during the conversion process.
Data Bit 0 to 7. These outputs are three-state TTL-compatible.
Positive power supply voltage, 2.7 V to 5.5 V.
