Product details
Overview
TLV2361CDBVT from Texas Instruments is a single-channel, low-voltage operational amplifier in SOT-23-5 package, designed for ±1 V to ±2.5 V supply operation. It delivers 7 MHz unity-gain bandwidth, 3 V/µs slew rate, ±2.4 V output swing (at ±2.5 V supplies), 8 nV/√Hz input noise, and 85 dB CMRR - enabling high-fidelity signal conditioning in battery-powered audio and sensor interfaces.
For engineers reviewing the TLV2361CDBVT datasheet, TLV2361CDBVT pinout, TLV2361CDBVT application, or TLV2361CDBVT equivalent, this page provides verified specifications, validated pin functions, real-world use cases in low-voltage analog front-ends, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The TLV2361CDBVT uses a proprietary Texas Instruments bipolar process optimized for low-voltage operation, supporting rail-to-rail output swing while maintaining stable AC performance down to ±1 V supplies. Its internal architecture includes matched transistor pairs for low input offset voltage (1–6 mV) and low input bias current (20–150 nA).
It operates across 0°C to 70°C ambient temperature, with absolute maximum ratings of ±3.5 V supply and ±3.5 V differential input voltage. Thermal resistance θJA is 206°C/W in the SOT-23-5 (DBV) package, requiring careful power dissipation management at full load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±1 V to ±2.5 V - enables direct operation from single-cell Li-ion or dual alkaline batteries without regulation. |
| Unity-Gain Bandwidth | 7 MHz typ at ±2.5 V - supports audio-band amplification and fast-sampling sensor signal chains up to ~1 MSPS. |
| Slew Rate | 3 V/µs typ at ±2.5 V - ensures <1% THD for 1.2 VPP signals up to 3 kHz, critical for low-distortion audio preamps. |
| Output Voltage Swing | ±2.4 V typ into 10 kΩ at ±2.5 V - delivers >95% of rail-to-rail dynamic range, maximizing ADC utilization in 3.3 V systems. |
| Input Noise Density | 8 nV/√Hz typ at 1 kHz - suitable for microphone preamplifiers and precision sensor interfaces where SNR > 90 dB is required. |
| CMRR | 85 dB typ at ±2.5 V - rejects common-mode interference in noisy industrial or automotive environments. |
| Input Offset Voltage | 1–6 mV max at 25°C - allows DC-coupled gain stages with <10 mV error in 10× amplification of millivolt-level transducer outputs. |
Pinout & Package
SOT-23-5 (DBV) package: 5-pin surface-mount, 1.45 mm max height, 2.9 × 1.6 mm footprint, thermal pad not present. Pin 1 marked by index area; tape-and-reel orientation Q3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail output swing; drives 10 kΩ loads with ±2.4 V swing at ±2.5 V supply. |
| 2 (IN−) | Inverting input | Differential input node with 5–100 nA offset current; requires matched trace impedance for optimal CMRR. |
| 3 (IN+) | Non-inverting input | High-impedance input (20–150 nA bias current); used for sensor reference or signal injection in instrumentation amps. |
| 4 (VCC−) | Negative supply rail | Connects to system ground or negative rail; must be decoupled with 0.1 µF ceramic capacitor near pin. |
| 5 (VCC+) | Positive supply rail | Accepts +1 V to +2.5 V; shared with other low-voltage rails in multi-amp designs to minimize supply count. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Zero-drift architecture; 10 µV max VIO, 0.1 µV/°C drift, but lower 350 kHz bandwidth and 0.16 V/µs slew rate. | Better DC precision for sensor offsets, but unsuitable for audio or fast transient response. | Choose OPA333AIDBVR when microvolt-level DC accuracy dominates over bandwidth or slew rate. |
| MCP6001T-E/OT | CMOS input; 100 nA max IIB, 1 MHz bandwidth, 0.6 V/µs slew rate, wider supply range (1.8–6.0 V), but higher 25 nV/√Hz noise. | Lower power (100 µA ICC) and better input impedance for high-Z sources, but noisier and slower. | Choose MCP6001T-E/OT for ultra-low-power, high-impedance pH or photodiode sensors where speed is secondary. |
Compared with TLV2361CDBVT, OPA333AIDBVR trades 7 MHz bandwidth for microvolt-level offset stability, while MCP6001T-E/OT reduces supply current by 93% but sacrifices 98% of slew rate and doubles input noise - making TLV2361CDBVT optimal for balanced low-voltage, low-noise, medium-speed analog signal paths.

FAQ
What is the maximum supply voltage for TLV2361CDBVT?
The absolute maximum supply voltage for TLV2361CDBVT is ±3.5 V, but the recommended operating range is ±1 V to ±2.5 V. Operation beyond ±2.5 V may degrade performance or reliability, and TI specifies guaranteed functionality only within the recommended range. Always observe derating guidelines for thermal management at elevated voltages.
Does TLV2361CDBVT support rail-to-rail input?
No, TLV2361CDBVT does not feature rail-to-rail input. Its common-mode input voltage range is specified as ±1.4 V at ±2.5 V supply (full temperature range), meaning inputs must stay within 1.4 V of each rail. However, it does provide rail-to-rail output swing - delivering ±2.4 V into 10 kΩ at ±2.5 V - making it ideal for output buffering in constrained supply systems.
Can TLV2361CDBVT drive capacitive loads directly?
TLV2361CDBVT is not unity-gain stable with heavy capacitive loads. The datasheet recommends limiting capacitive load to ≤100 pF for stable operation without external compensation. For larger loads (e.g., ADC input capacitance or long traces), a series isolation resistor (20–100 Ω) between TLV2361CDBVT output and the load is required to maintain phase margin and prevent oscillation.
What is the thermal resistance (θJA) of TLV2361CDBVT in its SOT-23-5 package?
The junction-to-ambient thermal resistance (θJA) for TLV2361CDBVT in the SOT-23-5 (DBV) package is 206°C/W, as specified in the Absolute Maximum Ratings table. This value assumes standard JEDEC test conditions (single-layer board, no copper pour). Real-world PCB layout with thermal vias and copper planes can reduce effective θJA by 30–50%, improving power handling capability.
Is TLV2361CDBVT RoHS compliant and lead-free?
Yes, TLV2361CDBVT is RoHS compliant and lead-free. TI's packaging addendum confirms "Yes" for RoHS status, with lead finish specified as NiPdAu (NIPDAU) or pure tin (SN), both fully compliant with EU RoHS Directive 2011/65/EU and China RoHS. The device carries Level-1 moisture sensitivity rating with unlimited floor life under dry pack conditions.
