AD624BDZ PRODUCT DESCRIPTION

The AD624 is a high precision, low noise, instrumentationamplifier designed primarily for use with low level transducers,including load cells, strain gauges and pressure transducers. Anoutstanding combination of low noise, high gain accuracy, lowgain temperature coefficient and high linearity make the AD624ideal for use in high resolution data acquisition systems.The AD624C has an input offset voltage drift of less than0.25 µV/°C, output offset voltage drift of less than 10 µV/°C,CMRR above 80 dB at unity gain (130 dB at G = 500) and amaximum nonlinearity of 0.001% at G = 1. In addition to theseoutstanding dc specifications, the AD624 exhibits superior acperformance as well. A 25 MHz gain bandwidth product, 5 V/µsslew rate and 15 µs settling time permit the use of the AD624 inhigh speed data acquisition applications.The AD624 does not need any external components for pre-trimmed gains of 1, 100, 200, 500 and 1000. Additional gainssuch as 250 and 333 can be programmed within one percentaccuracy with external jumpers. A single external resistor canalso be used to set the 624’s gain to any value in the range of 1to 10,000.
