PRODUCT DESCRIPTION

PRODUCT HIGHLIGHTS

The AD624 is a high precision, low noise, instrumentation

amplifier designed primarily for use with low level transducers,

including load cells, strain gauges and pressure transducers. An

outstanding combination of low noise, high gain accuracy, low

gain temperature coefficient and high linearity make the AD624

ideal for use in high resolution data acquisition systems.

1. The AD624 offers outstanding noise performance. Input

noise is typically less than 4 nV/√Hz at 1 kHz.

2. The AD624 is a functionally complete instrumentation am-

plifier. Pin programmable gains of 1, 100, 200, 500 and 1000

are provided on the chip. Other gains are achieved through

the use of a single external resistor.

The AD624C has an input offset voltage drift of less than

0.25 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 a

maximum nonlinearity of 0.001% at G = 1. In addition to these

outstanding dc specifications, the AD624 exhibits superior ac

performance as well. A 25 MHz gain bandwidth product, 5 V/µs

slew rate and 15 µs settling time permit the use of the AD624 in

high speed data acquisition applications.

3. The offset voltage, offset voltage drift, gain accuracy and gain

temperature coefficients are guaranteed for all pretrimmed

gains.

4. The AD624 provides totally independent input and output

offset nulling terminals for high precision applications.

This minimizes the effect of offset voltage in gain ranging

applications.

5. A sense terminal is provided to enable the user to minimize

the errors induced through long leads. A reference terminal is

also provided to permit level shifting at the output.

The AD624 does not need any external components for pre-

trimmed gains of 1, 100, 200, 500 and 1000. Additional gains

such as 250 and 333 can be programmed within one percent

accuracy with external jumpers. A single external resistor can

also be used to set the 624’s gain to any value in the range of 1

to 10,000.
