The ADA4661-2ACPZ-R7 from Analog Devices is a dual 20MHz rail-to-rail I/O op-amp with 1.8-5.5V supply, low 500uA/ch current, and excellent DC precision in compact LFCSP-8.

The ADA4661-2ACPZ-R7 is a dual 20MHz rail-to-rail I/O operational amplifier from Analog Devices in LFCSP-8, operating from 1.8V to 5.5V with 700uA supply current per amplifier. The CMOS input stage provides true rail-to-rail input (both common-mode and differential), extending 200mV beyond both supply rails. The output swings to within 20mV of the rails with a 10k-ohm load. The 20MHz gain-bandwidth product and 10V/us slew rate support active filters and signal conditioning up to approximately 2MHz. The input bias current is 0.5pA typical, making it suitable for high-impedance sensor interfaces such as photodiode amplifiers and pH probes. The input offset voltage is 100uV typical (2mV max over temperature). The device achieves 7nV/sqrt(Hz) input voltage noise at 1kHz, which is low for a CMOS amplifier. The output can source/sink 30mA at 5V supply, sufficient for driving moderate loads and ADC inputs. The LFCSP-8 package (3x3mm with exposed paddle) provides 40C/W thermal resistance, allowing 100mW dissipation at 85C ambient. The device is unity-gain stable and internally compensated. The -ACPZ-R7 suffix specifies LFCSP-8, tape-and-reel. Key applications include battery-powered instrumentation, portable medical devices, and low-power signal conditioning.
