NEW DESIGNS consider the AD8274 or AD8276 difference amps for their wider bandwidth, smaller foot print, higher ESD performance and lower costs. The AMP03 is a monolithic unity-gain, high-speed differential amplifier. Incorporating a matched thin-film resistor network, the AMP03 features stable operation over temperature without requiring expensive external matched components. The AMP03 is a basic analog building block for differential amplifier and instrumentation amplifiers.
