LMP90080QMH

Texas Instruments · Analog Front End (AFE) · HTSSOP-28

LMP90080QMH from Texas Instruments, in a HTSSOP-28. 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 VA power_in Analog power supply pin, specified at +4.75 V to 5.5 V in the Operating Ratings.
2 VIN0 input Analog input pin; voltage on any analog input must stay within -0.3 V to VA+0.3 V per the Absolute Maximum Ratings.
3 VIN1 input Analog input pin; voltage on any analog input must stay within -0.3 V to VA+0.3 V per the Absolute Maximum Ratings.
4 VIN2 input Analog input pin; voltage on any analog input must stay within -0.3 V to VA+0.3 V per the Absolute Maximum Ratings.
5 VIN3 input Analog input pin; voltage on any analog input must stay within -0.3 V to VA+0.3 V per the Absolute Maximum Ratings.
6 VIN4 input Analog input pin; voltage on any analog input must stay within -0.3 V to VA+0.3 V per the Absolute Maximum Ratings.
7 VIN5 input Analog input pin; voltage on any analog input must stay within -0.3 V to VA+0.3 V per the Absolute Maximum Ratings.
8 VREFP1 input Positive reference input for the ADC; reference voltage operating range is +0.5 V to VA.
9 VREFN1 input Negative reference input for the ADC; reference voltage is referenced to GND and must keep VREF within +0.5 V to VA.
10 VIN6/VREFP2 input Analog input pin or, alternatively, the VREFP2 positive reference input.
11 VIN7/VREFN2 input Analog input pin or, alternatively, the VREFN2 negative reference input.
12 IB2 output Matched excitation current source for external RTD/sensor use, selectable from 100 µA to 1000 µA in 100 µA steps.
13 IB1 output Matched excitation current source for external RTD/sensor use, selectable from 100 µA to 1000 µA in 100 µA steps.
14 XOUT output External crystal oscillator connection output.
15 XIN/CLK input External crystal oscillator connection or external clock input.
16 GND power_in Power supply ground; all voltages are measured with respect to this pin.
