Product Introduction
The ADA4661-2 is a dual, precision, rail-to-rail input/output amplifier optimized for low power consumption, high bandwidth, and wide supply voltage range applications.
The ADA4661-2 is guaranteed to meet rated performance at supply voltages of 3.0 V, 10 V, and 18 V. The device is an ideal choice for 3.3 V, 5 V, 10 V, 12 V, and 15 V single-supply, as well as ±2.5 V, ±3.3 V, and ±5 V dual-supply applications. It employs a proprietary trimming technique to achieve very low offset voltage. In addition, the unique design architecture of the ADA4661-2 delivers excellent power supply rejection, common-mode rejection, and offset voltage performance when operating over a common-mode voltage range of −VSY + 1.5 V to +VSY − 1.5 V.
The ADA4661-2 is rated over the −40°C to +125°C extended industrial temperature range and is available in 8-lead MSOP and 8-lead LFCSP (3 mm × 3 mm) packages.
