Quad 40-V precision amplifier is generated by Intersil Corp. It has the features of high ESD and low power to provide excellent DC accuracy and noise performance. The new quad amplifiers are ideally for 12-bit to 24-bit process control, data acquisition and instrumentation applications. The models include ISL28407, ISL28417 and ISL28408.

The ISL28417 delivers very high performance while consuming only 530 µA maximum per channel, with low frequency noise of 250 nV peak-peak (0.1 Hz to1 to 10 Hz) and 8 nV/√Hz at 1 kHz. And it is designed for sensor front ends, DAC buffering, precision voltage regulation or low noise instrumentation applications that require a diverse range of signals. Its Offset voltage is 70 µV maximum, with offset drift of only 0.75 µV/℃ maximum.

The ISL28407’s low offset of 90 µV maximum and offset drift of 0.8 µV/℃ maximum provide high DC accuracy over temperature. It features an industry-leading combination of low power (290 µA maximum per channel), 1 MHz bandwidth, low input bias current drift (0.3 pA/℃) and low noise (13 nV/√Hz at 1 kHz). The ISL28407 operates from 4.5 V to 40 V with an ultra-low bias current drift of 0.3 pA/℃ over temperature (-40 to +85℃), which is 30 percent lower than competitive quad precision amps.

The ISL28408 features half the power consumption of the ISL28417 with single supply operation and rail-to-rail output. Its wide input voltage range supports input signals down to 0.5 V below the negative supply rail. The wide dynamic range rail-to-rail output, low offset of 230 µV maximum, low noise (15.8 nV/√Hz at 1 kHz) and low power (250 µA maximum per channel) with a wide voltage range single supply (3 V to 40 V) or dual supply (±1.5 V to ±20 V) make the ISL28408 ideal for industrial and instrumentation applications.
