Product details
Overview
TLV2361CDBV from Texas Instruments is a single-channel, low-voltage operational amplifier in SOT-23-5 package, designed for ±1 V to ±2.5 V dual-supply operation. It delivers 7 MHz unity-gain bandwidth, 3 V/µs slew rate, ±2.4 V output swing (at ±2.5 V supply), 8 nV/√Hz input noise, and operates across 0°C to 70°C ambient range - enabling high-fidelity signal conditioning in battery-powered audio and sensor front-ends.
For engineers reviewing the TLV2361CDBV datasheet, TLV2361CDBV pinout, TLV2361CDBV application, or TLV2361CDBV equivalent, key selection criteria include low-voltage rail-to-rail output capability, bipolar process stability at sub-2V supplies, thermal performance in DBV package (θJA = 206°C/W), and compatibility with space-constrained portable designs requiring minimal quiescent current (2.5 mA max per amplifier).
Technical Context
The TLV2361CDBV employs a proprietary Texas Instruments bipolar process optimized for low-voltage operation without sacrificing bandwidth or slew rate. Its internal architecture supports stable closed-loop gain down to unity while maintaining phase margin under capacitive loads up to 100 pF.
It features rail-to-rail output swing (±2.4 V at ±2.5 V supply, RL = 10 kΩ), common-mode input voltage range extending to ±1.4 V (full temperature range), and integrated ESD protection exceeding 2 kV HBM - making it suitable for direct interfacing with ADCs, DACs, and analog sensors in mixed-signal embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±1 V to ±2.5 V - enables operation from single 2 V Li-ion or dual alkaline cells without level-shifting circuitry. |
| Unity-Gain Bandwidth | 7 MHz typ at ±2.5 V - supports audio-band amplification and fast-settling sensor signal chains up to ~1 MHz closed-loop. |
| Slew Rate | 3 V/µs typ at ±2.5 V - ensures <1 µs settling to 0.1% for 2 VPP signals, critical for pulse amplification and active filters. |
| Output Voltage Swing | ±2.4 V typ at ±2.5 V, RL = 10 kΩ - maximizes dynamic range in low-voltage systems, reducing need for gain staging. |
| Input Noise Density | 8 nV/√Hz typ at 1 kHz - preserves SNR in microphone preamps and precision instrumentation front-ends. |
| Quiescent Current | 2.5 mA max per amplifier - balances performance and battery life in always-on wearable and IoT sensor nodes. |
| Operating Temperature | 0°C to 70°C - qualified for commercial-grade portable electronics, including handheld medical devices and consumer audio. |
Pinout & Package
SOT-23-5 (DBV) package: 5-pin surface-mount, 1.45 mm max height, 2.9 mm × 1.6 mm footprint, exposed pad optional per layout guidelines. Thermal resistance θJA = 206°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail output swing; requires minimum 10 kΩ load for full spec compliance. |
| 2 (IN−) | Inverting input | High-impedance node (IIB ≤ 150 nA); differential input voltage rating ±3.5 V. |
| 3 (IN+) | Non-inverting input | Common-mode range extends to ±1.4 V over full temperature; matched to IN− for offset minimization. |
| 4 (VCC−) | Negative supply rail | Reference for all internal biasing; must be connected directly to ground or negative rail with low-impedance path. |
| 5 (VCC+) | Positive supply rail | Accepts up to +3.5 V absolute max; decoupling capacitor (0.1 µF) required within 2 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Low-voltage operation | Functional at ±1 V supply - eliminates need for charge pumps or boost converters in ultra-low-power systems. |
| Wide output swing | ±2.4 V at ±2.5 V supply - increases usable signal headroom by >30% vs. legacy low-voltage op-amps. |
| Low distortion | 0.004% THD+N at 3 kHz - meets Class AB audio line-driver requirements without external compensation. |
| Bipolar process fidelity | 85 dB CMRR and 80 dB PSRR at 25°C - maintains accuracy in noisy mixed-signal PCB environments. |
| Robust ESD rating | ≥2 kV HBM - reduces risk of field failure during handling and board assembly without added protection diodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-channel low-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2371CDBV | Higher 3 MHz GBW, lower 1.25 mA IQ, but reduced output swing (±1.2 V at ±1.5 V) and higher 17 nV/√Hz noise. | Better suited for ultra-low-power sensor buffers where bandwidth <1 MHz suffices and noise is less critical. | Choose TLV2371CDBV only when quiescent current is primary constraint and full output swing is not required. |
| OPA316IDBVR | CMOS input (0.2 pA IB), 10 MHz GBW, 6 V/µs slew, but requires ≥1.8 V supply and has higher 11 nV/√Hz noise. | Ideal for high-impedance pH or photodiode sensors where input bias current dominates error budget. | Select OPA316IDBVR when interfacing with MΩ-range sources; avoid if operating below ±1.5 V or requiring lowest noise. |
Compared with TLV2361CDBV, TLV2371CDBV trades bandwidth and noise for lower power, while OPA316IDBVR offers superior input impedance and speed at the cost of higher supply voltage and noise - making TLV2361CDBV the optimal balance for general-purpose low-voltage audio and precision analog in commercial temperature range.

FAQ
What is the maximum supply voltage rating for TLV2361CDBV?
The TLV2361CDBV has absolute maximum supply voltage ratings of +3.5 V on VCC+ and −3.5 V on VCC−, meaning the total differential supply must not exceed 7 V. Operation beyond ±2.5 V is not recommended, as electrical characteristics are only specified up to ±2.5 V per the datasheet, and reliability may degrade outside this range. Always observe derating guidelines for long-term stability.
Does TLV2361CDBV support rail-to-rail input operation?
No, TLV2361CDBV does not feature rail-to-rail input. Its common-mode input voltage range is specified as ±1.4 V (minimum) over the full temperature range when VCC± = ±2.5 V, meaning inputs must remain within 1.4 V of each supply rail. This excludes direct connection to VCC+ or VCC− without attenuation or level shifting, unlike true RRI op-amps.
Can TLV2361CDBV drive capacitive loads reliably?
Yes, TLV2361CDBV is characterized for stable operation with up to 100 pF capacitive load when configured with closed-loop gain ≥ 40 (AV = 40), as verified in the datasheet's operating characteristics table. For unity-gain or higher capacitance, external compensation (e.g., series resistor at output) is required to prevent peaking or oscillation.
What is the thermal resistance (θJA) of TLV2361CDBV in its SOT-23-5 package?
The junction-to-ambient thermal resistance (θJA) for TLV2361CDBV in the SOT-23-5 (DBV) package is 206°C/W, as stated in the Absolute Maximum Ratings table. This value assumes standard JEDEC test board conditions (2-layer board, 1 in² copper). Actual thermal performance improves significantly with PCB copper pour and thermal vias under the exposed pad area.
Is TLV2361CDBV pin-compatible with other members of the TLV236x family?
Yes, TLV2361CDBV shares identical pinout with TLV2361IDBVT and TLV2361IDBVR (same SOT-23-5 DBV package), differing only in temperature grade (0°C to 70°C vs. −40°C to 85°C) and packaging quantity. It is not pin-compatible with TLV2362 dual-channel variants, which use 8-pin packages (SOIC, VSSOP, TSSOP) and have different pin assignments.
