PIN FUNCTION DESCRIPTION
Pin
No.
Mnemonic Function
1VINA
Analog Input.
2VINB
Analog Input.
3
AGND
Analog Ground.
4VREF
Voltage Reference Input. This is normally tied to VDD.
5
CS
Chip Select. Active Low Logic input. The device is selected when this input is active.
6
CONVST
Convert Start. A low to high transition on this input puts the track/hold into hold mode and starts con-
version. This input is asynchronous to the CLKIN and is independent of CS and RD.
7
RD
Read. Active Low Logic Input. This input is used in conjunction with CS low to enable data outputs.
8
BUSY
Active Low Logic Output. This status line indicates converter status. BUSY is low during conversion.
9
CLKIN
Clock Input. TTL-compatible logic input. Used as the clock source for the A/D converter. The mark/
space ratio of the clock can vary from 40/60 to 60/40.
10
DGND
Digital Ground.
11 . . . 22
DB0–DB11 Three-State Data Outputs. These become active when CS and RD are brought low.
23
MODE
MODE Input. This input is used to put the device into the power save mode (MODE = 0 V). During
normal operation, the MODE input will be a logic high (MODE = VDD).
24
VDD
Power Supply. This is nominally +5 V.
