**Analog Devices** · Pre-ordered Chips · LFCSP-16(3x3)

AD5593RBCPZ-RL7 from Analog Devices, in a LFCSP-16(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Power supply input that operates from 2.7 V to 5.5 V and should be decoupled with a 0.1 µF capacitor to GND. |
| 2 | I/O0 | bidirectional | Input/Output 0, independently configurable as DAC output, ADC input, or general-purpose digital input or output through the configuration registers. |
| 3 | I/O1 | bidirectional | Input/Output 1, independently configurable as DAC output, ADC input, or general-purpose digital input or output through the configuration registers. |
| 4 | I/O2 | bidirectional | Input/Output 2, independently configurable as DAC output, ADC input, or general-purpose digital input or output through the configuration registers. |
| 5 | I/O3 | bidirectional | Input/Output 3, independently configurable as DAC output, ADC input, or general-purpose digital input or output through the configuration registers. |
| 6 | VREF | power_in | Reference input/output that provides the 2.5 V internal reference when enabled (0.1 µF capacitor to GND recommended) or accepts an external reference of 1 V to VDD when the internal reference is disabled. |
| 7 | VLOGIC | power_in | Interface power supply with a voltage range of 1.8 V to 5.5 V. |
| 8 | I/O4 | bidirectional | Input/Output 4, independently configurable as DAC output, ADC input, or general-purpose digital input or output through the configuration registers. |
| 9 | I/O5 | bidirectional | Input/Output 5, independently configurable as DAC output, ADC input, or general-purpose digital input or output through the configuration registers. |
| 10 | I/O6 | bidirectional | Input/Output 6, independently configurable as DAC output, ADC input, or general-purpose digital input or output through the configuration registers. |
| 11 | I/O7 | bidirectional | Input/Output 7, independently configurable as DAC output, ADC input, or general-purpose digital input or output through the configuration registers. |
| 12 | GND | power_in | Ground reference point for all circuitry. |
| 13 | SDA | bidirectional | I2C serial data line, bidirectional open-drain, used with SCL to clock data in or out, and must be pulled to the VLOGIC supply with an external pull-up resistor. |
| 14 | SCL | input | I2C serial clock line, used with SDA to clock data in to or out of the 16-bit input register. |
| 15 | RESET | input | Asynchronous reset pin that is tied high for normal operation and resets the device to its default configuration when brought low. |
| 16 | A0 | input | Address input that sets the LSB of the 7-bit slave address. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
