FastFETs are an entirely new class of amplifiers from Analog Devices, of which the AD8034 and AD8065 are the first two parts to be released. FastFETs combine the desirable specs of FET input amps (high input impedance that almost eliminates the need to consider the input bias current in designs) with those of ADI's proprietary XFCB technology (most especially low power consumption, low noise and distortions, and a wide supply voltage). We believe FastFETs will change the way designers think about amplifiers in general, and FET amps specifically.Certainly any designers currently using FETs will certainly be interested in a high-performance and high-speed FET amp that uses a fraction of the power, in packages as small as SC-70.AD8033 (Single amp) SOIC-8 and SC70AD8034 (Dual amp) SOIC-8 and SOT23-8

The AD8452 combines a precision analog front-end controller and switch mode power supply (SMPS), pulse-width modulator (PWM) driver into a single silicon platform for high volume battery testing and formation manufacturing. A precision instrumentation amplifier (in-amp) measures the battery charge/discharge current, while an equally accurate difference amplifier measures the battery voltage. Internal laser trimmed resistor networks establish the in-amp and difference amplifier gains (66 V/V and 0.4 V/V, respectively), and stabilize the AD8452 performance across the rated operating temperature range.Desired battery cycling current and voltage levels are established by applying precise control voltages to the ISET and VSET inputs. Actual charge and discharge current levels are sensed (usually by a high power, highly accurate shunt resistor) whose value is carefully selected according to system parameters. Switching between constant current (CC) and constant voltage (CV) loop integration is instantaneous, automatic, and completely transparent to the observer. A logic high at the MODE input selects the charge or discharge mode (high for charge, low for discharge).The AD8452 simplifies designs by providing excellent performance, functionality, and overall reliability in a space saving 48-lead, 7 mm × 7 mm × 1.4 mm LQFP package rated for operation at temperatures from −40°C to +85°C.Applications Battery formation and testing High efficiency battery test systems with recycle capability Battery conditioning (charging and discharging) systems
