INA333SKGD2

Instrumentation, Op Amps, Buffer Amps Overview

The INA333SKGD2 is a precision instrumentation amplifier die manufactured by Texas Instruments. It features zero-drift architecture with an input offset voltage of 10 µV and low input bias current of 70 pA. The device operates on a single supply voltage ranging from 1.8 V to 5.5 V, consuming only 50 µA of supply current. It provides a gain bandwidth product of 150 kHz and a slew rate of 0.16 V/µs. The output is rail-to-rail, and it offers high common-mode rejection ratio (CMRR). This bare die component is designed for surface-mount integration into custom substrates.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix SKGD2 indicates the bare die configuration rather than a packaged variant. Confirm substrate compatibility and handling requirements for unpackaged semiconductor dies. Ensure design files match the exact revision specified in the official datasheet. Check for any specific assembly notes regarding die attachment and wire bonding procedures provided by Texas Instruments.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when ultra-low offset voltage and drift are critical alongside minimal power consumption. The bare die format requires custom PCB or substrate design capabilities. Compare against packaged INA333 variants if board space allows standard packages. Consider the 1.8 V minimum supply voltage constraint for low-voltage system designs.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the INA333 family of zero-drift instrumentation amplifiers. It shares core electrical characteristics with packaged versions like the INA333IDGKR but differs in physical form factor. The SKGD2 designation specifically identifies the exposed die version intended for advanced packaging solutions.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional equivalents include other INA333 series parts such as INA333IDGKR for packaged alternatives. Verify pinout and electrical specifications match exactly before substitution. No direct pin-compatible bare die substitutes are publicly confirmed.
