About the AD8506
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 minimizing distortion through its power supplies and its inputs. Its 105-dB PSR minimizes errors caused by power supply voltage variations over a battery’s lifetime, making the AD8506 ideal for battery powered applications. Furthermore, the AD8506 maintains 105-dB CMR, maximizing linearity by minimizing the common-mode induced distortion often found in amplifiers having rail-to-rail inputs.
While maintaining high linearity, the AD8506 consumes only 20 µA of supply current per amplifier—35 percent 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 is ideally suited for use with Analog Devices’ 16-bit, low-power, low-voltage data converters, including the AD7683/AD7684/AD7685 and the AD7680.

Availability and Pricing
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 $0.70 per unit in 1,000-piece quantities.
