Overview
The AD7887ARM-REEL7, produced by Analog Devices Inc., is a high-performance, low-power, 12-bit analog-to-digital converter (ADC). This component operates from a single 2.7 V to 5.25 V power supply and is capable of a throughput rate of 125 kSPS. The AD7887 features a single-ended sampling scheme and can be configured for either single-channel or dual-channel operation. It is housed in an 8-lead Mini Small Outline Package (MSOP) or Small Outline IC (SOIC) package, making it suitable for space-constrained applications.
