NAME
NO.
I/O
DESCRIPTION
AIN
4
I
Analog input
CS/Powerdown
1
I
Chip Select. A low on this input enables the TLV1572. A high disables the device and disconnects the power
to the TLV1572.
DO
8
O
Serial data output. A/D conversion results are provided at this output pin.
FS
7
I
Frame sync input in DSP mode. The falling edge of the frame sync pulse from DSP indicates the start of
a serial data frame shifted out of the TLV1572. The FS input is tied to VCC when interfacing to a
micro-controller.
GND
3
Ground
SCLK
5
I
Serial clock input. This clock synchronizes the serial data transfer and is also used for internal data
conversion.
VCC
6
Power supply, recommend connection to analog supply
VREF
2
I
Reference voltage input. The voltage applied to this pin defines the input span of the TLV1572.
