The differential input rejects common-mode noise, and the parallel data interface makes it straightforward to read into a microcontroller or latch without a serial clock. It runs on ±5 V supplies for both the analog and digital sections, and requires an external voltage reference — typical for ratiometric measurements where the reference tracks the sensor excitation. ## Through-hole package for repair and prototyping Housed in a 40-lead PDIP (0.600\" wide body, 15.24 mm row spacing), this part is through-hole only — no surface-mount variant. The commercial temperature range (0°C to 70°C) covers most benchtop instruments, panel meters, and industrial controllers that live indoors. If your application sees -40°C, this isn't the grade.","metaTitle":"ICL7109CPL+ ADC 12-Bit Dual Slope 40-DIP, 30 SPS","metaDescription":"Analog Devices ICL7109CPL+ 12-bit dual-slope ADC, 30 SPS, differential input, parallel interface, 40-PDIP.
