Product details
Overview
TLV365DBVR from Texas Instruments is a single-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 fast 0.2µs settling to 0.01% - enabling precision ADC driving in low-side current sensing and audio front-ends.
For engineers reviewing the TLV365DBVR datasheet, TLV365DBVR pinout, TLV365DBVR application, or TLV365DBVR equivalent, key selection considerations include zero-crossover distortion topology, rail-to-rail operation down to 2.2V supply, ±20pA max input bias current, 2µV/°C max offset drift, and SOT-23-5 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV365DBVR implements a zero-crossover input stage that eliminates common-mode transition distortion across the full rail-to-rail input range (extending 100mV beyond both supplies), ensuring linear performance in ADC driver and sensor interface applications. Its CMOS architecture supports true rail-to-rail output swing within 10mV of either rail at 2.2V–5.5V operation.
It features a 56° phase margin at unity gain, stable drive into capacitive loads up to 100pF (with recommended RISO), and no power-down mode - operating exclusively in high-performance linear mode across −40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth | 50MHz - enables accurate amplification of signals up to ~10MHz with ≤3dB gain error in closed-loop configurations |
| Slew Rate | 27V/µs - supports clean 4V step response in ≤200ns, critical for SAR ADC acquisition timing |
| Input Voltage Noise | 4.5nV/√Hz - preserves SNR in low-level sensor and audio signal paths |
| CMRR | 115dB typical - rejects supply and common-mode interference in noisy industrial environments |
| Offset Drift | 2µV/°C maximum - ensures <±0.3mV total offset shift over −40°C to +125°C, vital for precision measurement |
| Supply Range | 2.2V to 5.5V - compatible with Li-ion, 3.3V, and 5V systems without level-shifting |
| Settling Time | 0.2µs to 0.01% - meets tight acquisition windows of 14-bit+ SAR ADCs |
Pinout & Package
TLV365DBVR is housed in a 5-pin SOT-23 (DBV) package, 2.9mm × 1.6mm × 1.15mm, with exposed pad not electrically connected. Designed for reflow soldering and high-density placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT | Output | Rail-to-rail output capable of sourcing/sinking >50mA; settles within 10mV of V+ or V− under load |
| −IN | Inverting Input | High-impedance CMOS node; accepts common-mode voltages from (V−) −0.1V to (V+) +0.1V |
| +IN | Noninverting Input | Zero-crossover topology ensures no distortion or offset discontinuity across full input range |
| V− | Negative Supply | Reference for all internal biasing; supports single-supply (ground) or split-supply (e.g., −1V) operation |
| V+ | Positive Supply | Maximum 6V absolute rating; 5.5V max recommended for continuous operation |
Key Features
| Feature | Design Value |
|---|---|
| Zero-crossover input topology | Eliminates CMRR degradation and offset nonlinearity at rail crossings - essential for accurate DC-coupled sensor interfaces |
| Rail-to-rail input and output | Enables full dynamic range utilization in single-supply systems (e.g., 0–3.3V ADC inputs) without external level-shifting |
| Ultra-low input bias current | ≤20pA max ensures minimal loading on high-impedance sources like piezoelectric sensors or pH electrodes |
| Fast overdrive recovery | <100ns recovery from output saturation - prevents errors in low-side current sensing during ground-bounce events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA365AIDBVR | Same 50MHz GBW and rail-to-rail I/O, but higher 5.8mA quiescent current vs TLV365DBVR's 4.6mA; 25V/µs slew rate vs 27V/µs | Better dc precision (120dB CMRR, 0.1µV/°C drift) but lower power efficiency | Select OPA365AIDBVR when ultra-low offset drift dominates over supply current in battery-powered designs |
| TLV9061IDBVR | Lower 10MHz GBW, 6.5V/µs slew rate, but significantly lower 560µA quiescent current and same 2.2V–5.5V supply range | Optimized for always-on, low-power signal conditioning - not suitable for >1MHz closed-loop bandwidths | Select TLV9061IDBVR only when bandwidth demand is ≤1MHz and micro-power operation is mandatory |
Compared with OPA365AIDBVR and TLV9061IDBVR, TLV365DBVR uniquely balances 50MHz bandwidth, 27V/µs slew rate, and 4.6mA supply current in a 5-pin SOT-23 - making it the optimal choice for cost-sensitive, space-constrained, high-speed ADC driver applications requiring rail-to-rail operation down to 2.2V.

FAQ
What is the maximum supply voltage for TLV365DBVR?
The absolute maximum supply voltage (VS = V+ − V−) for TLV365DBVR is 6V. However, the recommended operating range is 2.2V to 5.5V. Exceeding 5.5V continuously risks reliability degradation and is outside guaranteed specifications per the datasheet's Recommended Operating Conditions table.
Does TLV365DBVR support true rail-to-rail input beyond the supply rails?
Yes. TLV365DBVR's zero-crossover input stage allows common-mode voltage operation from (V−) − 0.1V to (V+) + 0.1V - meaning it accepts inputs up to 100mV beyond both supply rails. This capability is explicitly confirmed in Section 6.5 Electrical Characteristics and Figure 7-1 of the TLV365DBVR datasheet.
Can TLV365DBVR drive a capacitive load without oscillation?
TLV365DBVR is unity-gain stable and can drive capacitive loads up to 100pF with acceptable overshoot when using the recommended isolation resistor (RISO) per Figure 7-5. For loads >100pF or demanding low-overshoot requirements, adding RISO (e.g., 20Ω for 100pF) is required - confirmed in Section 7.3.3 and Figure 6-16.
What is the typical input bias current of TLV365DBVR at room temperature?
The typical input bias current of TLV365DBVR at 25°C is ±5pA, with a maximum of ±20pA over the full −40°C to +125°C temperature range. This value is specified in Table 6-5 under "INPUT BIAS CURRENT" and validated in Figure 6-5 showing measured distribution across units.
Is TLV365DBVR suitable for driving a 14-bit SAR ADC like the ADS7945?
Yes. TLV365DBVR is explicitly used as an ADC driver in TI's reference design (Figure 8-7), delivering 0.2µs settling to 0.01% and low 4.5nV/√Hz noise - meeting the acquisition time and SNR requirements of 14-bit, 2MSPS SAR ADCs such as the ADS7945. Its 50MHz GBW and 27V/µs slew rate ensure reliable capacitor charging.
