MAX40023ANT+

Instrumentation, Op Amps, Buffer Amps Overview

The MAX40023ANT+ is a single-channel, low-noise, low-power instrumentation amplifier manufactured by Analog Devices / Maxim Integrated. It operates within a supply voltage range of 1.6V to 3.6V and is specified over an operating temperature range of -40°C to +125°C. The device features a typical quiescent current of 17µA per channel and an ultra-low input bias current of less than 1pA at room temperature. Key electrical parameters include a gain-bandwidth product of 80kHz, a slew rate of 20mV/µs, and an input voltage noise density of 32nV/√Hz. It is housed in a space-saving 6-bump wafer-level package (WLP) with a 0.4mm bump pitch.

• Integrated internal EMI rejection capabilities
• Power-saving shutdown mode that reduces supply current to approximately 55nA

Instrumentation, Op Amps, Buffer Amps Applications

• Wearable medical devices
• Industrial sensors
• Battery-powered devices

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'ANT+' corresponds to the 6-bump WLP package configuration when sourcing. Confirm RoHS compliance status as indicated by the '+' suffix. Ensure compatibility with the required 0.4mm pitch land pattern for surface-mount assembly. Cross-reference the manufacturer part number against official distributor catalogs to validate availability and authenticity before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring minimal power consumption alongside very low leakage currents. It is suitable for interfacing with high-output impedance voltage sources or current sources such as photodiodes and pH sensors. Consider the 6-bump WLP package constraints regarding thermal resistance on single-layer versus four-layer PCBs during layout planning.

Instrumentation, Op Amps, Buffer Amps Part Context

The MAX40023ANT+ belongs to the MAX40023/MAX40024 family of amplifiers designed for precision applications. While the MAX40024 offers dual channels, the MAX40023 provides a single-channel solution. Both share identical electrical characteristics but differ in pin count and package options, including SOT23 and TDFN variants for different footprint requirements.
