2 / 12 page ![]() ML2340, ML2350 2 PIN NAME FUNCTION PIN NAME FUNCTION 1VCC Positive supply. 2VOUT Voltage output of the D/A converter. VOUT is referenced to VZS. 3VZS 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. 4 AGND Analog ground. 5 DGND 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. 6 DB0 Data input — Bit 0 (LSB). 7 DB1 Data input — Bit 1. PIN DESCRIPTION 8 DB2 Data input — Bit 2. 9 DB3 Data input — Bit 3. 10 DB4 Data input — Bit 4. 11 DB5 Data input — Bit 5. 12 DB6 Data input — Bit 6. 13 DB7 Data input — Bit 7 (MSB). 14 XFER Transfer enable input. The data is transferred into the transparent latch at the high level of XFER. 15 GAIN 0 Digital gain setting input 0. 16 GAIN 1 Digital gain setting input 1. 17 VREF OUT 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. 18 VREF IN Voltage reference input. VREF IN is referenced to AGND.
