ISL28633FVZ

Overview

The ISL28633FVZ is a single-channel, zero-drift programmable gain instrumentation amplifier from Renesas Electronics. It operates on a supply voltage range of 2.5 V to 5.5 V and features rail-to-rail input and output capabilities. Key electrical parameters include an input offset voltage (Vos) of 600 nV, an input bias current (Ib) of 400 pA, and a common-mode rejection ratio (CMRR) of 80 dB. The device offers a gain-bandwidth product of 2.3 MHz and a power supply rejection ratio (PSRR) of 140 dB. It draws 3 mA of operating current and functions within a temperature range of -40°C to +125°C. The component is housed in a TSSOP-14 package.

Feature Summary

• Zero-drift architecture ensures low offset voltage and minimal drift over time and temperature.
• Programmable gain functionality supported by a unique 2-bit, 3-state logic interface for flexible signal conditioning.
• Rail-to-rail input and output stages maximize dynamic range in low-voltage applications.

Applications

• High precision industrial sensor signal conditioning
• Medical instrumentation data acquisition
• Strain gauge and bridge circuit amplification

Procurement Notes

Verify the specific suffix 'FVZ' against the manufacturer's official datasheet to confirm the TSSOP-14 package type and lead-free status. Ensure the logic interface requirements match your system's control lines. Confirm moisture sensitivity level handling during assembly. Cross-reference the part number with the latest Renesas documentation to validate availability and any recent design changes.

Selection Notes

Select this component when high accuracy and stability are required in single-supply systems. The zero-drift technology eliminates the need for external chopper stabilization circuits. Consider the 2.3 MHz bandwidth and 800 mV/us slew rate for signal frequency requirements. The 3 mA current consumption suits battery-operated or power-sensitive designs compared to traditional chopper amplifiers.

Part Context

The ISL28633 belongs to the ISL2863x series of 5V programmable gain instrumentation amplifiers. This family shares core zero-drift technology but varies in output configuration; the ISL28633 provides a single-ended output, whereas variants like the ISL28634 offer differential outputs. All members utilize the same 2-bit logic interface for gain selection and share similar electrical characteristics regarding offset and noise performance.
