IN/OUT
DESCRIPTION
EQUIVALENT CIRCUIT
VINx-
Input
Amplifier x inverting input, where:
x = A for EL9200
x = A, B for EL9201
x = A, B, C, D for EL9202
VINx+
Input
Amplifier x non-inverting input, where:
x = A for EL9200
x = A, B for EL9201
x = A, B, C, D for EL9202
Reference Circuit 1
VS+
Supply
Op amp supply; bypass to GND with 0.1F capacitor
VOUTX
Output
Amplifier X output, where:
x = A for EL9200
x = A, B for EL9201
x = A, B, C, D for EL9202
NC
-
No connect; not internally connected
GND
Supply
Ground connection
IOUT
Output
Adjustable sink current output pin; the current sinks into the
OUT pin is equal to the DAC setting times the maximum
adjustable sink current divided by 128; see SET pin function
description for the maxim adjustable sink current setting
SET
Output
Maximum sink current adjustment point; connect a resistor
from SET to GND to set the maximum adjustable sink
current of the OUT pin; the maximum adjustable sink
current is equal to (AVDD/20) divided by RSET
CE
Input
Counter enable pin; connect CE to VDD to enable counting
of the internal counter; connect CE to GND to inhibit
counting
CTL
Input
Internal counter up/down control and internal EEPROM
programming control input; if CE is high, a mid-to-low
transition increments the 7-bit counter, raising the DAC
setting, increasing the OUT sink current, and lowering the
divider voltage at OUT; a mid-to-high transition decrements
the 7-bit counter, lowering the DAC setting, decreasing the
OUT sink current, and increasing the divider voltage at
OUT; applying 4.9V and above with appropriately arranged
timing will overwrite EEPROM with the contents in the 7-bit
counter; see EEPROM Programming section for details
AVDD
Supply
Analog voltage supply; bypass to GND with 0.1F
capacitor
VSD
