●Product Details
●The AD526 is a single-ended, monolithic software programmable gain amplifier (SPGA) that provides gains of 1, 2, 4, 8 and 16. It is complete, including amplifier, resistor network and TTL-compatible latched inputs, and requires no external components.
●Low gain error and low nonlinearity make the AD526 ideal for precision instrumentation applications requiring programmable gain. The small signal bandwidth is 350 kHz at a gain of 16. In addition, the AD526 provides excellent dc precision. The FET-input stage results in a low bias current of 50 pA. A guaranteed maximum input offset voltage of 0.5 mV max (C grade) and low gain error (0.01%, G = 1, 2, 4, C grade) are accomplished using Analog Devices" laser trimming technology.
●To provide flexibility to the system designer, the AD526 can be operated in either latched or transparent mode. The force/sense configuration preserves accuracy when the output is connected to remote or low impedance loads.
●The AD526 is offered in one commercial (0°C to +70°C) grade, J, and three industrial grades, A, B and C, which are specified from -40°C to +85°C. The S grade is specified from -55°C to +125°C. The military version is available processed to MIL-STD 883B, Rev C. The J grade is supplied in a 16-pin plastic DIP, and the other grades are offered in a 16-pin hermetic side-brazed ceramic DIP.
