PIN FUNCTION DESCRIPTIONS

No.

Mnemonic

Description

1VREF

Reference Input, 1.2 V to VDD.

2VIN

Analog Input, 0 V to VREF.

3

GND

Analog and Digital Ground.

4

CONVST

Convert Start. A low-to-high transition on this pin initiates a 1

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 AD7819

automatically powers down.

5

CS

Chip Select. This is a logic input.

CS is used in conjunction with RD to enable outputs.

6

RD

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.

7

BUSY

ADC Busy Signal. This is a logic output. This signal goes logic high during the conversion process.

8–15

DB0–DB7

Data Bit 0 to 7. These outputs are three-state TTL-compatible.

16

VDD

Positive power supply voltage, +2.7 V to +5.5 V.

DIP/SOIC
