pin FuncTions
LTC1595
VREF (Pin 1): Reference Input.
RFB(Pin2):FeedbackResistor.Normallytiedtotheoutput
of the current to voltage converter op amp.
OUT1 (Pin 3): Current Output Pin. Tie to inverting input
of current to voltage converter op amp.
GND (Pin 4): Ground Pin.
LD (Pin 5): The Serial Interface Load Control Input. When
LD is pulled low, data is loaded from the shift register into
the DAC register, updating the DAC output.
SRI (Pin 6): The Serial Data Input. Data on the SRI pin
is latched into the shift register on the rising edge of the
serial clock. Data is loaded MSB first.
CLK (Pin 7): The Serial Interface Clock Input.
VDD (Pin 8): The Positive Supply Input. 4.5V ≤ VDD ≤ 5.5V.
Requires a bypass capacitor to ground.
LTC1596/LTC1596-1
OUT1 (Pin 1): True Current Output Pin. Tie to inverting
input of current to voltage converter op amp.
OUT2 (Pin 2): Complement Current Output Pin. Tie to
analog ground.
AGND (Pin 3): Analog Ground Pin.
STB1, STB2, STB3, STB4 (Pins 4, 8, 10, 11): Serial
Interface Clock Inputs. STB1, STB2 and STB4 are rising
edge triggered inputs. STB3 is a falling edge triggered
input (see Truth Tables).
LD1, LD2 (Pins 5, 9): Serial Interface Load Control Inputs.
When LD1 and LD2 are pulled low, data is loaded from
the shift register into the DAC register, updating the DAC
output (see Truth Tables).
SRO (Pin 6): The Output of the Shift Register. Becomes
valid on the active edge of the serial clock.
SRI (Pin 7): The Serial Data Input. Data on the SRI pin
is latched into the shift register on the active edge of the
serial clock. Data is loaded MSB first.
DGND (Pin 12): Digital Ground Pin.
CLR (Pin 13): The Clear Pin for the DAC. Clears DAC to
zero-scale when pulled low on LTC1596. Clears DAC to
mid-scale when pulled low on LTC1596-1. This pin should
be tied to VDD for normal operation.
VDD (Pin 14): The Positive Supply Input. 4.5V ≤ VDD
5.5V. Requires a bypass capacitor to ground.
VREF (Pin 15): Reference Input.
RFB(Pin16):FeedbackResistor.Normallytiedtotheoutput
of the current to voltage converter op amp.
