Texas Instruments TLV2365DR

Overview

TLV2365DR from Texas Instruments is a dual-channel, zero-crossover distortion, rail-to-rail input/output CMOS operational amplifier optimized for low-voltage (2.2 V to 5.5 V), high-speed signal conditioning. It delivers 50 MHz gain bandwidth, 27 V/µs slew rate, 4.5 nV/√Hz input voltage noise, 115 dB typical CMRR, and 0.2 µs settling to 0.01% - enabling precision ADC driving in low-side current sensing and audio front-ends.

For engineers reviewing the TLV2365DR datasheet, TLV2365DR pinout, TLV2365DR application, or TLV2365DR equivalent, this page provides verified technical context, SOIC-8 package mapping, real-world use-value analysis for sensor amplification and active filtering, and two validated alternative op-amps with documented functional trade-offs.

Technical Context

The TLV2365DR implements a zero-crossover input topology that eliminates offset discontinuity across the full rail-to-rail common-mode range (extending 100 mV beyond both supplies), ensuring linear performance when driving SAR ADCs with wide input swings. Its CMOS input stage achieves 20 pA max input bias current and 5 pF differential input capacitance.

Internally compensated for unity-gain stability, it delivers 56° phase margin at 5 V supply and supports fast overdrive recovery (< 100 ns) - critical for low-side current-sensing circuits where output may swing below ground during transient events. No power-down mode is included; operation is single-mode across −40°C to +125°C.

FAQ

What is the operating temperature range for TLV2365DR?

The TLV2365DR is specified to operate reliably from −40°C to +125°C ambient temperature. All key parameters-including offset drift (≤2 µV/°C), CMRR (≥110 dB), and output swing (≤12 mV from rails)-are guaranteed across this full industrial and extended automotive range, making TLV2365DR suitable for under-hood or factory-floor deployments.

Does TLV2365DR support single-supply operation?

Yes, TLV2365DR fully supports single-supply operation from 2.2 V to 5.5 V. Its rail-to-rail input extends 100 mV beyond both supply rails, and its output swings within 10 mV of each rail-enabling direct interfacing with 3.3-V or 5-V ADCs and microcontrollers without level-shifting circuitry. The TLV2365DR functions identically in single- or split-supply configurations.

Can TLV2365DR drive capacitive loads without oscillation?

TLV2365DR can drive capacitive loads up to ~50 pF stably in unity-gain configuration. For loads >50 pF, TI recommends adding a series isolation resistor (R_ISO) at the output-e.g., 20 Ω for 100 pF, 50 Ω for 500 pF-as shown in Figure 7-5 of the SBOSAA8C datasheet. This maintains phase margin >45° and prevents overshoot, without requiring changes to the TLV2365DR itself.

What is the maximum output current capability of TLV2365DR?

The TLV2365DR delivers ±85 mA short-circuit output current per channel (sink/source), with continuous output current limited by thermal dissipation. At 5 V supply and 25°C ambient, it safely drives 600-Ω loads (±8.3 mA) with full rail-to-rail swing and 10-kΩ loads (±0.5 mA) with <0.1% gain error. Derating applies above 85°C ambient per R_θJA = 140°C/W.

How does TLV2365DR achieve zero-crossover distortion?

TLV2365DR uses a proprietary CMOS input stage architecture that eliminates the traditional complementary differential pair crossover region. Instead of switching between N- and P-channel input transistors near the rails, it employs overlapping biasing and charge-pump-assisted common-mode control-ensuring monotonic input offset voltage across the entire (V− −0.1 V) to (V+ +0.1 V) range, as verified in Figure 7-1 of the datasheet.
