PIN FUNCTIONS

PIN

NAME

FUNCTION

1

VDD

Power Supply Voltage, +2.7V to +3.6V.

2

AIN

Analog Signal Input; Unipolar, 0 to VREF input range.

3

SH

Active-Low Shutdown Input. Toggling

SH

high-to-low powers down the TS7003 and reduces

the supply current to 0.2μA (typ).

4

GND

Analog and igital Ground. Connect the TS7003’s G

pin at one and only one point to the

system analog ground plane.

5

REF

Reference Voltage for Analog-to-Digital Conversion

– an internal 2.5V reference output. Bypass

with a good-

quality 4.7μF capacitor.

6

CS

Active-Low Chip Select. The

CS signal initiates the conversion process on its falling edge. When

the CS input is logic high, DOUT is high impedance.

7

DOUT

Serial-Data Output. DOUT tog

gles state on SCLK’s rising edge and is high impedance when CS

is logic high.

8

SCLK

Serial-Clock Input. The SCLK signal controls the conversion process and transfers output data

at rates up to 4.8MHz.
