ALD4704BPBL

Overview

The ALD4704BPBL is a quad rail-to-rail CMOS operational amplifier manufactured by Advanced Linear Devices Inc. It features a unity gain bandwidth of 2.1 MHz and a slew rate of 5 V/µs. The device operates on dual supply voltages ranging from ±3.25 V to ±5 V, or single supplies up to 10 V. Input offset voltage is typically 2 mV with input bias current as low as 1 pA typical. It utilizes a 14-pin Small Outline Plastic DIP (SOIC) package.
