DESCRIPTION
D0:D11
1:12
I
Parallel data input port for the dual I-DACs; MSB = D11, LSB = D0; interleaved operation.
DGND
13
Digital ground of I-DAC
+VD
CLK
14
Digital supply of I-DAC; 2.7V to 3.3V
15
I
Clock input of I-DAC
PD
16
I
Power-down pin; active high; a logic high initiates power-down mode.
STBY
17
I
Standby pin of I-DAC; active low; a logic low initiates Standby mode with PD = Low.
A logic high configures the I-DAC for normal operation; pin will resume a high state if left open.
CS
18
I
Chip select; active low; enables the parallel data port of the I-DACs.
Pin will resume a low state if left open.
GSET
19
I
Gain-setting mode. A logic high enables the use of two separate full-scale adjust resistors on pins FSA1
and FSA2. A logic low allows the use of a common full-scale adjust resistor connected to FSA1. The
function of the FSA2 pin is disabled, and any remaining resistor has no effect. The value for the RSET
resistor remains the same for a given full-scale range, regardless of the selected GSET mode. Pin will
resume a low state if left open.
DGND
20
Digital ground of I-DAC
AGND
21
Analog ground of I-DAC
AGND
22

FSA2
23
I
Full-scale adjust of I-DAC2; connect external gain setting resistor RSET2 = 19.6k
.
Full-scale adjust of I-DAC1; connect external gain setting resistor RSET1 = 19.6k
.
External reference voltage input; internal reference voltage output; bypass with 0.1
μ
F to AGND for internal
reference operation.
