# ZJC2541-16BSABR

**ZJW** · Digital To Analog Converters (DACs) · SOIC-8

ZJC2541-16BSABR from ZJW, in a SOIC-8. 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 | VOUT | output | DAC voltage output, unbuffered, with output range 0 V to VREF and about 6.25 kΩ output impedance. |
| 2 | AGND | power_in | Analog ground. |
| 3 | REF | input | Voltage reference input, with a range of 2 V to VDD and code-dependent input resistance, so it should be driven from a low impedance source. |
| 4 | CS | input | Serial digital chip select input, active low. |
| 5 | SCLK | input | Serial data clock input, with data clocked in on the rising edge and a maximum frequency of 50 MHz. |
| 6 | DIN | input | Serial data input, loaded MSB first into the 16-bit word. |
| 7 | DGND | power_in | Digital ground. |
| 8 | VDD | power_in | Supply voltage input, 2.7 V to 5.5 V, with an absolute maximum of 6 V relative to AGND. |
