FUNCTION

Positive supply.

Voltage output of the D/A converter.

VOUT is referenced to VZS.

Zero Scale Voltage. VOUT is referenced

to VZS. VZS is normally tied to AGND

in the unipolar mode or to mid-supply

in the bipolar mode. When the device

is operated from a single power

supply, VZS has a maximum current

requirement of –300µA in the bipolar

mode.

Analog ground.

Digital ground. This is the ground

reference level for all digital inputs.

The range is AGND - DGND - VCC –

4.5V. DGND is normally tied to

system ground.

Data input — Bit 0 (LSB).

Data input — Bit 1.

FUNCTION

Data input — Bit 2.

Data input — Bit 3.

Data input — Bit 4.

Data input — Bit 5.

Data input — Bit 6.

Data input — Bit 7 (MSB).

Transfer enable input. The data is

transferred into the transparent latch at

the high level of XFER.

Digital gain setting input 0.

Digital gain setting input 1.

Voltage reference output. VREF OUT is

referenced to AGND. VREF OUT is set

to 2.5V and 5.0V in a low-voltage and

high-voltage operation, respectively

for the ML2350; 2.25V and 4.5V for

the ML2340.

Voltage reference input. VREF IN is

referenced to AGND.
