AD7278BRMZ
Analog Devices · Analog To Digital Converters (ADCs) · MSOP-8
AD7278BRMZ from Analog Devices, in a MSOP-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 | VDD | power_in | Power supply input; the VDD range for the AD7278 is 2.35 V to 3.6 V. |
| 2 | SDATA | output | Serial data out carrying the conversion result MSB first, clocked out on the falling edge of SCLK, with two leading zeros, 8 conversion bits and six trailing zeros for the AD7278. |
| 3 | CS | input | Active-low chip select that initiates conversion on its falling edge and frames the serial data transfer. |
| 4 | NC | unconnected | No connect pin. |
| 5 | NC | unconnected | No connect pin. |
| 6 | SCLK | input | Serial clock logic input that provides the data access clock and the clock source for the conversion process. |
| 7 | GND | power_in | Analog ground reference point for all circuitry; all analog input signals are referred to this GND voltage. |
| 8 | VIN | power_in | Single-ended analog input channel with an input range of 0 V to VDD. |
