Description
Analog Output Voltage of DAC C. Buffered output with a nominal full-scale output range of ±10 V. The output amplifier
is capable of directly driving a 10 kΩ, 200 pF load.
Ground Reference Pin for DAC C Output Amplifier.
Ground Reference Pin for DAC B Output Amplifier.
Analog Output Voltage of DAC B. Buffered output with a nominal full-scale output range of ±10 V. The output amplifier
is capable of directly driving a 10 kΩ, 200 pF load.
Analog Output Voltage of DAC A. Buffered output with a nominal full-scale output range of ±10 V. The output amplifier
is capable of directly driving a 10 kΩ, 200 pF load.
Ground Reference Pin for DAC A Output Amplifier.
External Reference Voltage Input for Channel A and Channel B. Reference input range is 1 V to 7 V; programs the
full-scale output voltage. REFIN = 5 V for specified performance.
External Reference Voltage Input for Channel C and Channel D. Reference input range is 1 V to 7 V; programs the
full-scale output voltage. REFIN = 5 V for specified performance.
Reference Output. This is the reference output from the internal voltage reference. The internal reference is 5 V ± 3
mV at 25°C, with a reference tempco of 10 ppm/°C.
Reference Ground Return for the Reference Generator and Buffers.
This pin provides an output voltage proportional to temperature. The output voltage is 1.4 V typical at 25°C die
temperature; variation with temperature is 5 mV/°C.
Determines the DAC Coding. This pin should be hardwired to either DV
CC
or DGND. When hardwired to DV
CC
, input
coding is offset binary. When hardwired to DGND, input coding is twos complement (see Table 6).
