Product details
Overview
TLV2361CDBVR 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 supplies), 8 nV/√Hz input voltage noise, and 75–85 dB CMRR - enabling high-fidelity signal conditioning in battery-powered audio and sensor front-ends.
For engineers reviewing the TLV2361CDBVR datasheet, TLV2361CDBVR pinout, TLV2361CDBVR application, or TLV2361CDBVR equivalent, key selection considerations include its rail-to-rail output capability at ultra-low supply voltage, thermal performance in SOT-23 (θJA = 206°C/W), and compatibility with space-constrained portable instrumentation requiring low-noise, low-distortion amplification.
Technical Context
The TLV2361CDBVR uses a proprietary Texas Instruments bipolar process optimized for low-voltage operation without sacrificing bandwidth or slew rate. Its internal architecture supports stable unity-gain configuration with minimal phase margin degradation across supply voltages from ±1 V to ±2.5 V.
It features matched transistor pairs and precision resistor networks to achieve 1–6 mV input offset voltage (typical 1 mV at 25°C) and 75–85 dB common-mode rejection, making it suitable for DC-coupled transducer interfaces where offset drift and supply ripple rejection are critical.
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 two-cell alkaline systems without LDO pre-regulation. |
| Unity-Gain Bandwidth | 7 MHz typ at ±2.5 V - supports audio-band amplification and active filter designs up to ~1 MHz closed-loop gain. |
| Slew Rate | 3 V/µs typ at ±2.5 V - ensures <0.1% THD+N for 1.2 VPP signals at 3 kHz, critical for line-level audio buffering. |
| Output Voltage Swing | ±2.4 V typ into 10 kΩ at ±2.5 V - delivers >96% of rail-to-rail swing, maximizing dynamic range in low-voltage data acquisition. |
| Input Voltage Noise | 8 nV/√Hz typ at 1 kHz - enables clean amplification of µV-level sensor outputs (e.g., thermocouples, piezoresistive bridges). |
| CMRR | 85 dB typ at ±2.5 V - rejects power supply ripple and common-mode interference in noisy embedded environments. |
| Input Offset Voltage | 1 mV typ at 25°C - reduces DC error in precision gain stages without external trimming. |
Pinout & Package
SOT-23-5 (DBV) package: 2.9 mm × 1.6 mm × 1.45 mm body, single-row 5-pin surface-mount with gull-wing leads and exposed pad not present (non-PowerPAD variant). Thermal resistance θJA = 206°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-swinging output current up to ±20 mA; requires local bypass capacitor for stability in high-frequency applications. |
| 2 (IN−) | Inverting input | High-impedance node (IIB = 20–150 nA); connects to feedback network in standard op-amp configurations. |
| 3 (IN+) | Non-inverting input | High-impedance node with matched bias current; used for reference voltage injection or sensor signal routing. |
| 4 (VCC−) | Negative supply rail | Reference for internal biasing; must be decoupled to ground with ≥0.1 µF ceramic capacitor near pin. |
| 5 (VCC+) | Positive supply rail | Reference for internal biasing; shares same decoupling requirement as VCC− to minimize PSRR degradation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply operation | Functional down to ±1 V supply - eliminates need for charge pumps or boost converters in wearables and IoT nodes. |
| Wide output voltage swing | ±2.4 V into 10 kΩ at ±2.5 V - preserves >95% of theoretical dynamic range in 3 VPP systems. |
| Low distortion performance | 0.004% THD+N at 3 kHz - meets consumer audio line-driver requirements per IEC 60268-3. |
| Low input bias current | 20 nA typ at 25°C - minimizes voltage error across high-impedance source impedances (>100 kΩ). |
| Stable unity-gain configuration | Internally compensated for AV ≥ 1 - avoids external compensation components in buffer and gain-of-two circuits. |

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; 0.1 µV/°C offset drift vs. TLV2361CDBVR's 2 µV/°C; 350 kHz GBW vs. 7 MHz. | Better DC precision but insufficient bandwidth for audio or fast sensor response. | Select when microvolt-level DC accuracy dominates over speed; avoid for >100 kHz closed-loop designs. |
| MCP6001T-E/OT | Rail-to-rail input/output; 1 MHz GBW; 0.6 V/µs slew rate; operates down to 1.8 V single supply (no negative rail required). | Single-supply only; lacks bipolar process low-noise advantage (17 nV/√Hz vs. 8 nV/√Hz). | Select for cost-sensitive, single-rail systems where noise <10 nV/√Hz is not critical. |
Compared with OPA333AIDBVR and MCP6001T-E/OT, the TLV2361CDBVR uniquely balances 7 MHz bandwidth, 3 V/µs slew rate, and 8 nV/√Hz noise at ±1 V operation - making it optimal for battery-powered audio and medium-speed precision analog front-ends where both AC fidelity and low-voltage efficiency are mandatory.

FAQ
What is the minimum supply voltage required for stable operation of the TLV2361CDBVR?
The TLV2361CDBVR is specified for stable operation down to ±1 V dual supply (2 V total), as confirmed in the Recommended Operating Conditions table. At this voltage, it maintains functional bandwidth and output swing, though slew rate and bandwidth scale downward versus ±2.5 V operation. The absolute maximum rating limits supply to ±3.5 V, and operation below ±1 V is not characterized or guaranteed.
Does the TLV2361CDBVR support rail-to-rail input operation?
No, the TLV2361CDBVR does not feature rail-to-rail input. Its common-mode input voltage range is specified as ±1.4 V at ±2.5 V supply and ±0.5 V at ±1.5 V supply - meaning inputs must remain within 0.5–1.4 V of each supply rail. It does provide rail-to-rail *output* swing (±2.4 V at ±2.5 V), but input stage headroom limitations require careful biasing in single-supply configurations.
What is the thermal performance of the TLV2361CDBVR in its SOT-23-5 package?
The TLV2361CDBVR in SOT-23-5 (DBV) package has a junction-to-ambient thermal resistance (θJA) of 206°C/W, as documented in the Absolute Maximum Ratings table. This value assumes standard JEDEC PCB mounting conditions (2s2p copper). Derating is required above 70°C ambient; maximum allowable power dissipation at 70°C is approximately 390 mW before reaching the 150°C junction limit.
Can the TLV2361CDBVR drive capacitive loads without instability?
The TLV2361CDBVR is internally compensated for unity-gain stability but exhibits reduced phase margin with capacitive loads >100 pF. The datasheet recommends limiting load capacitance to ≤100 pF or adding a series isolation resistor (typically 10–100 Ω) between the output and capacitive load to maintain stability. For driving ADC input capacitors or long cables, external compensation or buffer staging is advised.
Is the TLV2361CDBVR RoHS compliant and lead-free?
Yes, the TLV2361CDBVR is RoHS compliant and lead-free, as confirmed in the Package Option Addendum: "RoHS: Yes" and "Lead finish/Ball material: NIPDAU | SN". It meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) with unlimited floor life at ≤30°C/60% RH, and is rated for reflow peak temperatures up to 260°C.
