CM1103-SOPTA

CIMO · Analog To Digital Converters (ADC) · MSOP-10

CM1103-SOPTA from CIMO, in a MSOP-10. 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 ADDR input I2C slave address selection pin; connect to GND, VDD, SDA, or SCL to select address per Table 4.
2 ALTER/RDY output Comparator output or conversion ready signal; open-drain output configurable via COMP_MODE register bit.
3 GND power_in Ground connection.
4 AIN0 input Analog input channel 0, selectable as positive or negative input in differential configuration or single-ended mode; voltage range GND-0.3V to VDD+0.3V.
5 AIN1 input Analog input channel 1, selectable as positive or negative input in differential configuration or single-ended mode; voltage range GND-0.3V to VDD+0.3V.
6 AIN2 input Analog input channel 2, selectable as positive or negative input in differential configuration or single-ended mode; voltage range GND-0.3V to VDD+0.3V.
7 AIN3 input Analog input channel 3, selectable as positive or negative input in differential configuration or single-ended mode; voltage range GND-0.3V to VDD+0.3V.
8 VDD power_in Positive supply voltage input; operating range 2.5V to 5V.
9 SDA bidirectional I2C serial data line, open-drain output; logic high threshold VIH=0.7VDD to VDD+0.3V, logic low threshold VIL=GND to 0.3VDD.
10 SCL input I2C serial clock input; logic high threshold VIH=0.7VDD to VDD+0.3V, logic low threshold VIL=GND to 0.3VDD.

CAD (KiCad official)

  • Symbol: CM1103-SOPTA
  • Footprint: Package_SO:MSOP-10_3x3mm_P0.5mm
  • 3D model: MSOP-10 (KiCad packages3D, STEP)
  • 3D model files: cm1103-sopta-etched.step / cm1103-sopta-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cm1103-sopta.step / cm1103-sopta.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: CIMO datasheet (23 pp, sha256 cde7136ef50865ec, retrieved 2026-09-29, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
