LMP91050MMX

Texas Instruments · Analog To Digital Converters (ADCs) · VSSOP-10-0.5mm

LMP91050MMX from Texas Instruments, in a VSSOP-10-0.5mm. 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 IN input Analog signal input, the input of the sensor signal path from the thermopile.
2 CMOUT output Analog common-mode voltage output, adjustable to 1.15 V or 2.59 V to increase output dynamic range.
3 A0 output First stage output, used for external filtering (high-pass, lowpass or bandpass) to remove out-of-band noise.
4 A1 input Second stage input, used for external filtering (high-pass, lowpass or bandpass) to remove out-of-band noise.
5 GND power_in Power ground.
6 OUT output Signal output, referenced to the same potential as CMOUT.
7 CSB input Chip select, active low, for the SPI interface.
8 SCLK input Interface clock for the SPI interface.
9 SDIO bidirectional Serial data input/output for the SPI interface.
10 VDD power_in Positive supply, 2.7 V to 5.5 V per the recommended operating conditions.
