MCP6033T-E/MS

Instrumentation, Op Amps, Buffer Amps Overview

The MCP6033T-E/MS is a single-channel precision operational amplifier from the MCP6031/2/3/4 family, manufactured by Microchip Technology. It operates on a single supply voltage ranging from 1.8V to 5.5V and features rail-to-rail input and output capabilities. The device includes a Chip Select (CS) pin for power management, drawing a typical quiescent current of 0.9 µA when active and reducing to 0.4 nA in shutdown mode. Key electrical specifications include a maximum input offset voltage of ±150 µV, a gain bandwidth product of 10 kHz, and a slew rate of 4 V/ms. It is housed in an 8-lead MSOP package and supports an extended operating temperature range from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Features a dedicated Chip Select (CS) digital input that enables low-power shutdown mode with minimal current draw and high-impedance output state.
• Provides rail-to-rail input and output operation, allowing signal swing close to both supply rails without phase reversal.
• Delivers high precision with a maximum input offset voltage of ±150 µV and ultra-low quiescent current suitable for battery-powered systems.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'E/MS' corresponds to the MSOP-8 package and industrial temperature grade during procurement. Confirm the presence of the Chip Select functionality inherent to the MCP6033 variant. Ensure compatibility with standard surface-mount assembly processes for the specified package type.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring precise amplification of low-frequency signals within a constrained power budget. The inclusion of the Chip Select feature makes it ideal for portable devices where extending battery life through deep sleep modes is critical. Ensure the required bandwidth does not exceed the 10 kHz specification.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MCP6031/2/3/4 family of zero-drift or low-offset CMOS operational amplifiers. While the MCP6031 is a single channel without shutdown, the MCP6033 adds the Chip Select capability. The MCP6032 and MCP6034 provide dual and quad configurations respectively, sharing the same core electrical characteristics and package options.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional equivalents within the same family include the MCP6031T-E/MS (without CS), MCP6032T-E/MS (dual), and MCP6034T-E/MS (quad). Cross-vendor replacements require matching the 1.8V-5.5V supply range, rail-to-rail I/O, and low offset voltage specifications.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the Chip Select pin affect the amplifier's output?

When the Chip Select (CS) pin is pulled high, the amplifier enters a low-power mode where the output goes into a high-impedance state and the supply current drops significantly.

What is the minimum operating supply voltage for this device?

The MCP6033T-E/MS can operate with a single supply voltage as low as 1.8V.
