MN86157
Stand-alone A/D converter (MODE pin at "L" level,
A10 pin at "L" level)
• In this configuration, the chip functions as a par-
allel A/D converter consisting of 128 chopper
comparators.
Resolution: 7 bits
Non-linearity: ±1/2 LSB
Conversion speed: max. 5 MHz
Analog input range: 3V p-p
(V_DD 5V)
• Clock mode selection
The A11 pin provides a choice of two clock
modes.
A11
Input Clock Conditions
CKSH: Supply a clock signal with a frequency
twice that of the input image clock. *1
L
SHST: Supply the A/D start signal for use in
synchronizing phase.
CKSH: Supply a clock signal with a
frequency twice that of the input
H
image clock. *2
ENBI: Supply a clock signal with the same
frequency as the input image clock.
Notes
*1: ENBI
*2: SHST: Keep this pin at "H" level.
