Texas Instruments OPA2363AIDGSR

Overview

OPA2363AIDGSR from Texas Instruments is a dual-channel, rail-to-rail input/output CMOS operational amplifier optimized for low-voltage, single-supply operation (1.8 V to 5.5 V). It delivers 7 MHz gain-bandwidth, 5 V/µs slew rate, and 90 dB typical CMRR, with ±10 pA input bias current and 500 µV max input offset voltage. It is used in battery-powered sensor signal conditioning, microphone preamplification, and data acquisition front-ends.

For engineers reviewing the OPA2363AIDGSR datasheet, OPA2363AIDGSR pinout, OPA2363AIDGSR application, or OPA2363AIDGSR equivalent, key selection criteria include its dual-channel shutdown capability, 10-pin VSSOP package, –40°C to +125°C operating range, rail-to-rail I/O swing within 10 mV of rails, and low 750 µA/channel quiescent current at 5.5 V.

Technical Context

The OPA2363AIDGSR implements a complementary CMOS input stage that eliminates crossover distortion, enabling high CMRR (90 dB typ) without degradation of differential linearity when driving ADCs. Its unity-gain stable architecture supports precision active filtering and low-noise amplification down to 1.8 V supply.

Each channel features independent enable control (Enable A on Pin 5, Enable B on Pin 6), rail-to-rail output swing (10 mV from rails at 10 kΩ load), and input common-mode range extending 0.1 V beyond both supply rails. Shutdown mode reduces quiescent current to <1 µA per channel.

FAQ

What is the maximum supply voltage for the OPA2363AIDGSR?

The OPA2363AIDGSR supports a maximum supply voltage of 5.5 V across the V+ to V– terminals. Operation beyond this limit risks permanent damage, as specified in the Absolute Maximum Ratings table. The device is fully characterized from 1.8 V to 5.5 V, making it ideal for 3.3 V and 5 V systems-and compatible with regulated 5.1 V supplies commonly used in industrial designs. Always ensure the voltage difference between V+ and V– does not exceed 5.5 V in the OPA2363AIDGSR.

Does the OPA2363AIDGSR support true rail-to-rail input and output operation?

Yes, the OPA2363AIDGSR supports rail-to-rail input common-mode range (V– – 0.1 V to V+ + 0.1 V) and rail-to-rail output swing (within 10 mV of each rail at 10 kΩ load). This enables full utilization of the supply voltage in single-supply configurations-critical for maximizing dynamic range in 1.8 V–5.5 V systems. The OPA2363AIDGSR achieves this without phase reversal or output latch-up, even when inputs exceed the rails by up to 0.5 V (with current limiting).

How does the shutdown feature work on the OPA2363AIDGSR?

The OPA2363AIDGSR provides independent shutdown control via two dedicated pins: Enable A (Pin 5) and Enable B (Pin 6). Driving either pin low (≤ V– + 0.8 V) disables its respective amplifier channel and reduces quiescent current to <1 µA. Driving it high (≥ 0.75 × V+) enables normal operation. The OPA2363AIDGSR's dual-enable architecture allows selective power gating-e.g., keeping Channel A active for bias generation while shutting down Channel B during idle periods-enabling fine-grained power optimization.

What is the input offset voltage specification for the OPA2363AIDGSR?

The OPA2363AIDGSR has a maximum input offset voltage of 500 µV at TA = 25°C and VS = 5 V, per the Electrical Characteristics table. This applies to the "I" grade variant (industrial), which the "AIDGSR" suffix confirms. The device also exhibits low drift (3 µV/°C max) across –40°C to +125°C, ensuring stable DC performance in temperature-varying environments. This precision makes the OPA2363AIDGSR suitable for applications like weigh scales and precision sensor bridges where offset-induced errors must be minimized.

Is the OPA2363AIDGSR unity-gain stable?

Yes, the OPA2363AIDGSR is unity-gain stable and requires no external compensation. Its internal compensation ensures stable operation with closed-loop gains ≥1, including voltage followers and active filters. This is confirmed in the Functional Block Diagram section and Typical Characteristics (Figure 1: Open-Loop Gain and Phase vs Frequency), which shows adequate phase margin (>45°) at unity gain. Designers can directly configure the OPA2363AIDGSR as a buffer or gain-of-1 amplifier without risk of oscillation-simplifying layout and reducing BOM count.
