PRODUCTION DATA
PIN | TYPE | DESCRIPTION | |
---|---|---|---|
NO. | NAME | ||
1 | FB0 | Input | Voltage
feedback pin for channel 0. In voltage-output mode, connect to OUT0 for closed-loop amplifier output. In current-output mode, keep the FB0 pin unconnected to minimize leakage current. |
2 | OUT0 | Output | Analog output voltage from DAC channel 0. |
3 | NC | NC | No connection. Leave this pin unconnected. |
4 | NC | NC | No connection. Leave this pin unconnected. |
5 | GPIO/SDO | Input/Output | General-purpose input/output configurable as
LDAC, PD,
PROTECT, RESET, SDO,
and STATUS. For STATUS and SDO, connect the pin to the IO voltage with an external pullup resistor. If unused, connect the GPIO pin to VDD or AGND using an external resistor. This pin can ramp up before VDD. |
6 | SCL/SYNC | Output | I2C serial interface clock or SPI chip select input. This pin must be connected to the IO voltage using an external pullup resistor. This pin can ramp up before VDD. |
7 | A0/SDI | Input | Address
configuration pin for I2C or serial data input for SPI.
For A0, connect this pin to VDD, AGND, SDA, or SCL for address configuration (Section 7.5.2.2.1). For SDI, this pin need not be pulled up or pulled down. This pin can ramp up before VDD. |
8 | SDA/SCLK | Input/Output | Bidirectional I2C serial data bus or SPI clock input. This pin must be connected to the IO voltage using an external pullup resistor in the I2C mode. This pin can ramp up before VDD. |
9 | NC | NC | No connection. Leave this pin unconnected. |
10 | NC | NC | No connection. Leave this pin unconnected. |
11 | OUT1/NC | Output/NC | DAC63002 and DAC53002: Analog output voltage from DAC channel 1. DAC63001 and DAC53001: No connection. Leave this pin unconnected. |
12 | FB1/NC | Input/NC | DAC63002 and DAC53002: Voltage feedback pin for channel 1. In
voltage-output mode, connect to OUT1 for closed-loop amplifier
output. In current-output mode, keep the FB0 pin unconnected to
minimize leakage current. DAC63001 and DAC53001: No-connect. Leave this pin unconnected. |
13 | CAP | Power | External bypass capacitor for the internal LDO. Connect a capacitor (approximately 1.5 μF) between CAP and AGND. |
14 | AGND | Ground | Ground reference point for all circuitry on the device. |
15 | VDD | Power | Supply voltage. |
16 | VREF | Power | External
reference input. Connect a capacitor (approximately 0.1 μF) between
VREF and AGND. Use a pullup resistor to VDD when the external reference is not used. This pin must not ramp up before VDD. In case an external reference is used, make sure the reference ramps up after VDD. |
Thermal pad | Thermal Pad | Ground | Connect the thermal pad to AGND. |
