Analog Input.
Analog Input.
Analog Ground.
Voltage Reference Input. This is normally tied to V
Chip Select. Active Low Logic input. The device is selected when this input is active.
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.
Read. Active Low Logic Input. This input is used in conjunction with CS low to enable data outputs.
Active Low Logic Output. This status line indicates converter status. BUSY is low during conversion.
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.
Digital Ground.
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 = V
Power Supply. This is nominally +5 V.
