Intersil releases JFET-input operational amplifier
Intersil
ISL28210 op amp
Intersil has introduced a JFET-input operational amplifier for process control analogue input/output, gas or fluid flow sensors and biometric high-impedance buffers for medical instrumentation.
The ISL28210 device, the first in a new range of JFET-input operational amplifiers, is also ideal for industrial applications requiring high-voltage signal conditioning such as data acquisition, ATE and power distribution systems.
The industrial temperature-grade, 40V-precision, JFET-input operational amplifier features a combination of low noise, low bias current, high slew rate, a fast settling time and low offset voltage.
The ISL28210 operates across a 9-40V voltage range.
It features bias current cancellation techniques that deliver optimal performance at 300 femto-amps, reducing signal conditioning errors in analogue input and making it ideal for high-performance designs.
The IS28210's input offset is just 300mV, with a typical offset drift of 1mV/oC.
Voltage noise is 580nVpp between 0.1Hz and 10Hz.
Input bias current is typically 300fA at 25C and a low 4.5pA maximum at 60C, making the device ideal for instrumentation amps, charge amps and photodiode amps for emerging medical and laboratory instrumentation.
The ISL28210 also delivers a slew rate of 20V/ms with a fast 900ns settling time, resulting in excellent transient performance for ATE and data acquisition analogue front-ends.
Designed on Intersil's proprietary precision silicon-on-insulator (SOI) bipolar process technology, the ISL28210 exhibits robust latch-up immunity and high electrostatic-discharge ratings of HBM 4keV and machine model 400V, so it performs optimally in harsh industrial environments over the -40C to +125C temperature range.
The ISL28210 is available now in an eight-lead SOIC package.
Pricing starts at USD1.69 (GBP1.07) each in 1,000-piece quantities.
