ADS1205IRGER from Texas Instruments, in a VQFN-24-EP(4x4). 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 | REFIN B | input | Reference voltage input of channel B, used for an external reference voltage. |
| 2 | AGND | power_in | Analog ground. |
| 3 | AVDD | power_in | Analog power supply, nominal 5V (AVDD specified 4.5 V to 5.5 V). |
| 4 | AVDD | power_in | Analog power supply, nominal 5V (AVDD specified 4.5 V to 5.5 V). |
| 5 | AGND | power_in | Analog ground. |
| 6 | CLKSEL | input | Clock select: CLKSEL = 1 selects the internal clock, CLKSEL = 0 selects the external clock. |
| 7 | CLKIN | input | External clock input (external clock range 16 MHz to 24 MHz for recommended operation; reduced accuracy down to 1 MHz to 33 MHz). |
| 8 | BVDD | power_in | Digital interface power supply, from 2.7 V to 5.5 V. |
| 9 | BGND | power_in | Interface (digital) ground. |
| 10 | CLKOUT | output | System clock output. |
| 11 | OUT B | output | Bit stream output from the channel B modulator. |
| 12 | OUT A | output | Bit stream output from the channel A modulator. |
| 13 | AGND | power_in | Analog ground. |
| 14 | REFOUT | output | Output of the internal reference source, nominal 2.5 V. |
| 15 | AVDD | power_in | Analog power supply, nominal 5V (AVDD specified 4.5 V to 5.5 V). |
| 16 | AVDD | power_in | Analog power supply, nominal 5V (AVDD specified 4.5 V to 5.5 V). |
| 17 | AGND | power_in | Analog ground. |
| 18 | REFIN A | input | Reference voltage input of channel A, used for an external reference voltage. |
| 19 | NC | unconnected | No connection; this pin is left unconnected. |
| 20 | CH A+ | input | Analog input of channel A, noninverting input. |
| 21 | CH A− | input | Analog input of channel A, inverting input. |
| 22 | CH B− | input | Analog input of channel B, inverting input. |
| 23 | CH B+ | input | Analog input of channel B, noninverting input. |
| 24 | NC | unconnected | No connection; this pin is left unconnected. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
