Frugal op amps maintain high linearity

CMOS dual op amp is designed for applications that require precision measurement at low voltage levels with minimal power consumption.

The AD8506 low-power CMOS dual operational amplifier with rail-to-rail inputs and output is designed for portable applications, including battery-powered patient monitors, remote sensors, handheld instrumentation and other mobile equipment that require precision measurement at low voltage levels with minimal power consumption.

Featuring a novel circuit architecture, the AD8506 maintains high linearity by minimising distortion through its power supplies and its inputs.

Its 105dB PSR minimises errors caused by power supply voltage variations over a battery's lifetime, making the AD8506 ideal for battery powered applications.

Furthermore, the AD8506 maintains 105dB CMR, maximising linearity by minimising the common-mode induced distortion often found in amplifiers having rail-to-rail inputs.

While maintaining high linearity, the AD8506 consumes only 20uA of supply current per amplifier - 35% less than other operational amplifiers in its class.

The combination of low power and high linearity delivers extended battery life for portable applications regardless of external conditions, allowing accurate measurement of real-world phenomenon in portable devices like tire pressure monitors, smoke detectors and glucose meters.

The AD8506 dual operational amplifier is available in an 8-lead MSOP.

It is sampling now, with full production quantities available in November 2007.

The AD8506 also is planned to be available in a tiny 8-bump WLCSP (wafer-level chip-scale package).

The AD8506 is priced at US $0.70 per unit in 1000-piece quantities.
