LMH6401IRMZR from Texas Instruments, in a UQFN-16(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SDI | input | Serial interface (SPI) input data pin. Receives register write data clocked in on SCLK when CS is asserted low. |
| 2 | INP | input | Positive differential analog signal input pin. Part of the 100-ohm differential input impedance signal path. |
| 3 | INM | input | Negative differential analog signal input pin. Part of the 100-ohm differential input impedance signal path. |
| 4 | SDO | output | Serial interface (SPI) output data pin. Provides read-back data from the register map. |
| 5 | VS- | power_in | Negative supply voltage. Tied to GND for single-supply 5.0-V operation, or to a negative rail for split-supply operation. Supply range: (VS+) - (VS-) = 4.0 V to 5.25 V. |
| 6 | PD | input | Power-down control pin. Logic 0 = amplifier enabled; logic 1 = amplifier disabled. |
| 7 | VOCM | input | Output common-mode voltage set pin. Drive this pin to set the amplifier's differential output common-mode level, typically to match the input common-mode of the downstream ADC. |
| 8 | VS+ | power_in | Positive supply voltage. Nominal 5.0 V (range 4.0 V to 5.25 V). Bypass to GND close to the pin. |
| 9 | GND | power_in | Ground reference for the device. Connect to the PCB ground plane. |
| 10 | OUTM | output | Negative differential output pin. Drives the negative side of the differential output through an internal 10-ohm series resistor. |
| 11 | OUTP | output | Positive differential output pin. Drives the positive side of the differential output through an internal 10-ohm series resistor. |
| 12 | GND | power_in | Ground reference for the device. Connect to the PCB ground plane. |
| 13 | VS+ | power_in | Positive supply voltage. Nominal 5.0 V (range 4.0 V to 5.25 V). Bypass to GND close to the pin. |
| 14 | SCLK | input | Serial interface (SPI) clock input. Clocks SDI in and SDO out while CS is asserted low. |
| 15 | CS | input | Active-low SPI chip select. Assert low to begin a SPI transaction; de-assert high to complete the transaction and latch data. |
| 16 | VS- | power_in | Negative supply voltage. Tied to GND for single-supply 5.0-V operation, or to a negative rail for split-supply operation. |
