Product details
Overview
TLV2365 from Texas Instruments is a dual-channel, rail-to-rail input/output CMOS operational amplifier optimized for low-voltage, high-speed signal conditioning. It delivers 50MHz gain bandwidth, 27V/µs slew rate, 4.5nV/√Hz voltage noise, 115dB typical CMRR, and operates from 2.2V to 5.5V - enabling precision ADC driving in low-side current sensing and audio front-ends.
For engineers reviewing the TLV2365 datasheet, TLV2365 pinout, TLV2365 application, or TLV2365 equivalent, this page provides verified package mapping (SOIC-8/D and VSSOP-8), confirmed dual-channel zero-crossover topology, real-world settling time (0.2µs to 0.01%), offset drift (≤2µV/°C), and validated alternatives for cost-sensitive, wideband analog designs.
Technical Context
The TLV2365 implements a zero-crossover distortion input stage that eliminates the common-mode transition region found in conventional rail-to-rail amplifiers, maintaining linear offset performance across the full input range - including 100mV beyond both supply rails. Its CMOS architecture enables ultra-low input bias current (≤20pA) and high input impedance.
This dual op-amp supports single-supply (2.2–5.5V) or split-supply operation with no power-down mode. It achieves fast overdrive recovery (<100ns), drives capacitive loads up to 100pF (with recommended RISO), and maintains stability at unity gain while delivering rail-to-rail output swing within 10mV of each rail.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth | 50MHz - enables stable closed-loop operation up to 25kHz with 2× gain, suitable for anti-aliasing filters ahead of 2MSPS SAR ADCs. |
| Slew Rate | 27V/µs - supports clean 4V step response in ≤200ns, critical for fast-settling ADC driver applications. |
| Input Voltage Noise | 4.5nV/√Hz at 500kHz - ensures minimal contribution to system SNR in sensor signal chains and audio preamps. |
| CMRR | 115dB typical (100–115dB min over temp) - rejects supply and common-mode interference in noisy industrial environments. |
| Offset Drift | ≤2µV/°C max - guarantees <±0.3mV total offset shift over −40°C to +125°C, essential for precision current sensing. |
| Rail-to-Rail I/O | Input extends 100mV beyond rails; output swings to within 10mV of rails - maximizes dynamic range in 3.3V systems. |
| Quiescent Current | 4.6mA per channel typical - balances speed and power for battery-powered instrumentation and portable test gear. |
Pinout & Package
TLV2365 is available in two 8-pin packages: SOIC (D) and VSSOP (DGK), both with identical pinout and thermal characteristics (RθJA = 140°C/W for D, 179°C/W for DGK).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V− | Negative supply | Lowest potential rail; must be connected to GND (single-supply) or negative voltage (dual-supply); supports −0.5V absolute min. |
| V+ | Positive supply | Highest potential rail; accepts 2.2–5.5V operating range; absolute max 6V; bypass with 0.1µF ceramic near pin. |
| +IN A / +IN B | Noninverting inputs | High-impedance CMOS inputs (≤20pA bias); accept common-mode voltage from (V−)−0.1V to (V+)+0.1V. |
| −IN A / −IN B | Inverting inputs | Differential pair inputs; enable standard op-amp configurations (inverting, noninverting, differential) per channel. |
| VOUT A / VOUT B | Amplifier outputs | Capable of sourcing/sinking ±85mA short-circuit current; swing to within 10mV of rails under 10kΩ load. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-crossover input topology | Eliminates input stage crossover distortion, ensuring linear CMRR >100dB across full input range - critical for accurate low-side shunt measurements. |
| Rail-to-rail input and output | Enables maximum signal swing in 2.2–5.5V systems; input includes both supply rails plus 100mV margin, output reaches within 10mV of rails. |
| Fast settling time | 0.2µs to 0.01% for 4V step - meets timing budgets for high-speed data acquisition with 2MSPS ADCs like ADS7042. |
| Ultra-low input bias current | ≤20pA max - prevents loading errors in high-impedance sensor interfaces (e.g., pH electrodes, piezoresistive bridges). |
| High-speed precision | Combines 50MHz GBW, 27V/µs slew rate, and 2µV/°C drift - rare in sub-5mA/op-amp class, ideal for cost-sensitive test equipment. |
Applications
| Low-Side Current Sensing | Audio Signal Conditioning |
|---|---|
Use Scenario: Measuring bidirectional motor current using a 10mΩ shunt resistor in a 3.3V microcontroller-based drive system. IC Role / Device Role / Timing Role: Dual-channel TLV2365 buffers and amplifies shunt voltage with rail-to-rail input to capture near-zero current events and fast transients.

IC Role / Device Role / Timing Role: First-stage gain block providing 20dB amplification with minimal added noise before anti-alias filtering. Use Value: 4.5nV/√Hz noise density preserves SNR; rail-to-rail output drives ADC input fully across 0–3.3V range without level-shifting. |
| ADC Driver for SAR Converters | Active Filter in Data Acquisition |
Use Scenario: Driving the input and reference pins of a 14-bit, 2MSPS SAR ADC (e.g., ADS7945) in an industrial sensor node. IC Role / Device Role / Timing Role: One channel conditions sensor signal; second channel buffers reference voltage, handling transient reference current demands. Use Value: 50MHz GBW and 27V/µs slew rate ensure full-scale steps settle to 0.01% in <200ns - meeting 500ns acquisition window. |
Use Scenario: Implementing a 500kHz Butterworth low-pass filter in a spectrum analyzer front-end to prevent aliasing. IC Role / Device Role / Timing Role: Single-op-amp MFB topology configured for second-order filtering with precise pole placement.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, high-speed, rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2365 | Same 50MHz GBW and 25V/µs slew rate; lower 3.8nV/√Hz noise; higher 0.9mA/channel quiescent current. | Better noise performance but higher power draw - preferred in ultra-low-noise audio where supply headroom allows. | Select OPA2365 when noise floor dominates design constraints and 0.9mA/channel IQ is acceptable. |
| TLV2762 | Lower 3MHz GBW, 1.3V/µs slew rate, 2.5µV/°C drift; 17µA/channel IQ; rail-to-rail I/O. | Optimized for micropower, not speed - suitable for battery-operated sensors requiring long runtime, not fast settling. | Choose TLV2762 only for always-on, low-bandwidth monitoring where µA-level IQ outweighs speed requirements. |
Compared with OPA2365 and TLV2762, TLV2365 uniquely balances 50MHz bandwidth, 27V/µs slew rate, and 4.6mA/channel IQ - making it the optimal choice for cost-sensitive, medium-power, high-fidelity signal chains requiring fast settling without excessive quiescent consumption.

FAQ
What is the maximum supply voltage for TLV2365?
The absolute maximum supply voltage (VS = V+ − V−) for TLV2365 is 6V. Operation is specified over 2.2V to 5.5V, with recommended derating above 5.5V to ensure reliability and avoid exceeding absolute ratings. Exceeding 6V may cause permanent damage.
Does TLV2365 support true rail-to-rail input beyond the supply rails?
Yes, TLV2365 supports input common-mode voltage from (V−) − 0.1V to (V+) + 0.1V - meaning it accepts signals up to 100mV beyond both supply rails. This capability is enabled by its zero-crossover input topology and is confirmed across −40°C to +125°C.
Can TLV2365 drive a 100pF capacitive load stably?
Yes, TLV2365 can drive up to 100pF capacitive loads stably in unity-gain buffer configuration when a series isolation resistor (RISO ≈ 20Ω) is added at the output, as documented in Figure 7-5 of the datasheet. Without RISO, instability may occur above ~20pF.
What is the guaranteed settling time for TLV2365 to 0.01%?
TLV2365 guarantees 0.2µs settling time to 0.01% for a 4V output step under recommended conditions (TA = 25°C, RL = 10kΩ). This value is tested and specified in Section 6.5 Electrical Characteristics of the datasheet.
Is TLV2365 suitable for driving SAR ADC reference inputs?
Yes, TLV2365 is explicitly recommended in TI's application notes (e.g., Figure 8-7) for driving SAR ADC reference pins due to its fast settling, high output drive (±85mA short-circuit), and ability to handle transient reference current demands without droop or instability.
