INA2133UA

Overview

The INA2133UA is a dual-channel, high-speed precision differential amplifier manufactured by Texas Instruments. It operates on a single supply voltage ranging from 4.5 V to 36 V and draws an operating supply current of 950 uA per device. The component features a gain-bandwidth product of 1.5 MHz and a slew rate of 4.5 V/us. Key electrical specifications include a common-mode rejection ratio of 80 dB and an input offset voltage of 450 uV. It supports a wide operating temperature range from -55°C to +125°C and is housed in a SOIC-14 surface-mount package.

Feature Summary

• Dual-channel architecture providing two independent high-speed precision differential amplifiers within a single integrated circuit.
• High-speed performance characterized by a 1.5 MHz gain-bandwidth product and a 4.5 V/us slew rate for rapid signal processing.
• Wide single-supply operation capability allowing functionality across a broad voltage spectrum from 4.5 V to 36 V.

Applications

• Industrial process control systems requiring precise differential signal conditioning
• Medical instrumentation equipment demanding high common-mode rejection capabilities
• Test and measurement devices utilizing high-speed data acquisition

Procurement Notes

Verify the specific suffix 'U' confirms the SOIC-14 tube packaging format when ordering. Confirm that the base part number corresponds to the standard INA2133 family specifications regarding bandwidth and offset voltage. Ensure compatibility with the required operating temperature range of -55°C to +125°C for your specific application environment before finalizing procurement.

Selection Notes

Select this component when a dual-channel solution is required for high-speed differential applications. The 80 dB CMRR and 450 uV Vos make it suitable for precision tasks where noise rejection is critical. Consider the SOIC-14 package dimensions for PCB layout constraints and verify that the 950 uA supply current fits within the system's power budget.

Part Context

The INA2133 belongs to Texas Instruments' portfolio of high-speed precision operational amplifiers. It is part of a series designed for applications requiring robust performance in noisy environments. The dual-channel configuration offers space savings compared to using two separate single-channel amplifiers, making it efficient for compact electronic designs.

Replacement Considerations

Check datasheets for other dual-channel differential amplifiers in the TI lineup. Verify pinout compatibility and electrical parameter overlaps such as GBP, slew rate, and supply voltage ranges before substituting.
