Texas Instruments 5962-9089504QPA

Overview

5962-9089504QPA from Texas Instruments is a Q-temp automotive-grade, chopper-stabilized operational amplifier optimized for ultra-low-noise, high-precision dc signal conditioning in harsh environments. It delivers 10 µV max input offset voltage, 0.05 µV/°C max offset drift, 13 nV/√Hz input noise at 1 kHz, 135 dB min open-loop gain, and operates from –40°C to +125°C with ±2.3 V to ±8 V dual supply. It is used in precision thermocouple amplifiers and strain gauge interfaces requiring stable offset over temperature.

For engineers reviewing the 5962-9089504QPA datasheet, 5962-9089504QPA pinout, 5962-9089504QPA application, or 5962-9089504QPA equivalent, key selection criteria include guaranteed 10 µV V_IO max over full automotive temperature range, chopper frequency of 10 kHz (no clock noise below 10 kHz), single-supply-compatible common-mode input range extending to V_DD–, and integrated output clamp functionality for fast overload recovery.

Technical Context

The 5962-9089504QPA employs Advanced LinCMOS™ process technology combined with continuous chopper-stabilization circuitry to null input offset voltage in real time across temperature, time, and supply variations. Its 10 kHz chopping frequency enables clean low-frequency noise performance while eliminating intermodulation error up to 5 kHz.

It features a rail-to-rail compatible input stage with common-mode range including the negative rail, internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015), and an output clamp pin that reduces overload recovery time. The device requires two external capacitors (C_XA, C_XB) for chopper operation but provides transparent user interface - no external clock required unless overriding default 10 kHz frequency via CLK IN/INT/EXT pins.

FAQ

What is the maximum input offset voltage specification for 5962-9089504QPA over its full operating temperature range?

The 5962-9089504QPA has a maximum input offset voltage of 10 µV at 25°C and 50 µV over its full –40°C to +125°C operating range, as specified in the TLC2654AQ electrical characteristics table. This value reflects the tighter V_IO grading of the 'A' variant (TLC2654A) under Q-temp qualification, ensuring predictable performance in automotive under-hood applications.

Does 5962-9089504QPA require an external clock source to operate?

No, the 5962-9089504QPA does not require an external clock source. Its internal chopper-control circuitry operates at a typical frequency of 10 kHz using only the two external capacitors CXA and CXB. External clocking via CLK IN and INT/EXT pins is optional and only needed if a non-standard chopping frequency is required - the default configuration is fully self-contained.

How does the CLAMP pin on 5962-9089504QPA improve system robustness?

The CLAMP pin on 5962-9089504QPA reduces output overload recovery time by actively limiting the output voltage swing during saturation. When asserted low, it engages an internal clamp circuit that holds the output near the supply rail, preventing deep saturation of internal nodes. This allows the 5962-9089504QPA to recover in microseconds rather than milliseconds - critical in closed-loop control systems where sustained saturation could cause instability.

Is 5962-9089504QPA compliant with MIL-PRF-38535, and what QML class does it meet?

Yes, 5962-9089504QPA is compliant with MIL-PRF-38535 and qualified to QML Class V. As a Q-suffix device in the TLC2654A family, it undergoes full military-level screening including burn-in, temperature cycling, and lot acceptance testing per MIL-STD-883, ensuring suitability for high-reliability aerospace and defense applications where failure modes must be rigorously controlled.

Can 5962-9089504QPA operate from a single supply, and what is its common-mode input range?

Yes, the 5962-9089504QPA supports true single-supply operation because its common-mode input voltage range includes the negative rail (V_DD–). With V_DD– tied to ground, inputs can swing from 0 V up to (V_DD+ – 2.3 V). This rail-included input stage eliminates the need for level-shifting networks in ground-referenced sensor interfaces such as thermocouples or bridge circuits.
