ISL28233IUZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28233IUZ is a dual-channel, micro-power, zero-drift operational amplifier featuring rail-to-rail input and output capabilities. It operates within a supply voltage range of 1.65 V to 5.5 V, consuming only 50 uA per channel. Key electrical specifications include a gain-bandwidth product of 400 kHz, a slew rate of 200 mV/us, an input offset voltage of 8 uV, and an input bias current of 110 pA. The device exhibits low input voltage noise density of 65 nV/sqrt Hz and input current noise density of 79 fA/sqrt Hz. It is housed in an MSOP-8 package and functions reliably across a temperature range of -40 C to +85 C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'T7' for tape-and-reel packaging when ordering, as the base part number may refer to tube packaging. Confirm RoHS compliance status through official Renesas documentation. Check for obsolescence notices, as Intersil products are managed under Renesas Electronics. Ensure ESD handling protocols are followed due to the sensitivity of the CMOS input stage.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low power consumption and high precision are required simultaneously. The zero-drift technology eliminates the need for external chopper stabilization circuits. Compare input bias current and offset voltage against standard bipolar amplifiers for improved accuracy in high-impedance source applications. Consider the MSOP-8 package size constraints for PCB layout optimization.
