Just received this in my mailbox, looks very good.
AD8641
The AD8641 is a low power, precision JFET input amplifier featuring 250 µA max supply current, 1 pA max input bias current, and 750 µV max offset voltage. High source impedance, low bias current, and low supply current are key to applications, such as ECG/EKG monitors, sleep monitoring, and blood analyzing instruments. The AD8641 is also ideal for applications utilizing multichannel boards that require low power to manage heat, such as photodiodes, precision active filters, and industrial controls. The ability to swing rail-to-rail at the output enables designers to buffer wide output swing devices in single-supply systems.
Low Supply Current: 250 µA max
Very Low Input Bias Current: 1 pA max
Low Offset Voltage: 750 µV max
V Noise Density 28.5nV/rtHz
Single-supply Operation: 5 V to 26 V
Dual-supply Operation: ±2.5 V to ±13 V
Rail-to-rail Output
Unity Gain Stable
No Phase Reversal
SC70 Package
