Dual op amp delivers low power, high linearity

Norwood, Mass. — Analog Devices Inc. has developed the AD8506 low-power CMOS dual operational amplifier with rail-to-rail inputs and output 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. The 105 dB PSR minimizes errors caused by power supply voltage variations over a battery's lifetime. 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 uA of supply current per amplifier, which is said to be 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 in portable devices such as tire pressure monitors, smoke detectors and glucose meters, said Analog Devices.

The AD8506 may be used with Analog Devices' 16-bit low-power, low-voltage data converters including the AD7683/AD7684/AD7685 and the AD7680.

Pricing: $0.70 per unit in quantities of 1,000.
Availability: Sampling now in an 8-lead MSOP, with full production quantities available in November 2007. The AD8506 is also planned to be available in a tiny
8-bump wafer-level chip-scale package (WLCSP).
