Product details
Overview
TLV2361CDBVTG4 from Texas Instruments is a single-channel, low-voltage operational amplifier in SOT-23-5 package, designed for rail-to-rail output swing at ±1 V minimum supply. It delivers 7 MHz unity-gain bandwidth, 3 V/µs slew rate, and ±2.4 V output voltage swing (at ±2.5 V supply, RL = 10 kΩ), enabling high-fidelity signal conditioning in battery-powered audio and sensor interfaces.
For engineers reviewing the TLV2361CDBVTG4 datasheet, TLV2361CDBVTG4 pinout, TLV2361CDBVTG4 application, or TLV2361CDBVTG4 equivalent, key selection criteria include low-supply operation down to ±1 V, wide output swing relative to supply rails, low input noise (8 nV/√Hz at 1 kHz), and compatibility with space-constrained portable designs using SOT-23 footprint.
Technical Context
The TLV2361CDBVTG4 employs a proprietary Texas Instruments bipolar process optimized for low-voltage performance, supporting dual-supply operation from ±1 V to ±2.5 V. Its architecture achieves high dynamic range through wide common-mode input voltage (±1.4 V at full temperature range) and high open-loop gain (60–80 dB).
It features internal compensation for unity-gain stability, operates across 0°C to 70°C ambient, and maintains low distortion (0.004% THD+N at 3 kHz) - critical for precision analog front-ends in portable instrumentation and audio preamplifiers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2371CDBVR | Higher supply current (2.9 mA vs 2.5 mA), lower noise (7 nV/√Hz), same SOT-23-5 package | Better suited for ultra-low-noise audio where power budget allows +0.4 mA per channel | Select TLV2371CDBVR when noise dominates design trade-off; TLV2361CDBVTG4 preferred for tighter supply current limits |
| OPA316IDBVR | Lower input bias current (0.2 pA vs 150 nA), higher GBW (10 MHz), same supply range and package | Superior for high-impedance sensor buffering (e.g., pH electrodes) where bias current induces offset error | Choose OPA316IDBVR for femtoampere-level input impedance; TLV2361CDBVTG4 remains optimal for cost-sensitive, general-purpose low-voltage gain |
Compared with TLV2371CDBVR and OPA316IDBVR, TLV2361CDBVTG4 offers the lowest quiescent current among these three while maintaining competitive noise and bandwidth - making it the most power-efficient choice for battery-operated signal chains where sub-2.5 mA/channel is critical.

FAQ
What is the maximum supply voltage rating for TLV2361CDBVTG4?
The absolute maximum supply voltage for TLV2361CDBVTG4 is ±3.5 V - meaning VCC+ must not exceed +3.5 V and VCC− must not fall below −3.5 V. Operation beyond this risks permanent damage. The recommended operating range is ±1 V to ±2.5 V per the datasheet, with guaranteed performance across that span. TLV2361CDBVTG4 is not rated for 5-V single-supply operation.
Does TLV2361CDBVTG4 support rail-to-rail input?
No, TLV2361CDBVTG4 does not feature rail-to-rail input. Its common-mode input voltage range is specified as ±1.4 V over the full temperature range (−40°C to 85°C for TLV2361I, but TLV2361CDBVTG4 is rated 0°C to 70°C). At ±2.5 V supply, this means inputs must stay within −1.1 V to +1.1 V relative to ground. The device does provide rail-to-rail *output* swing, however - up to ±2.4 V at ±2.5 V supply.
What is the thermal resistance (θJA) of TLV2361CDBVTG4 in its SOT-23-5 package?
The junction-to-ambient thermal resistance (θJA) for TLV2361CDBVTG4 in the SOT-23-5 (DBV) package is 206°C/W, as confirmed in the Absolute Maximum Ratings table of the official datasheet. This value assumes standard JEDEC test board conditions (2-layer board, 1 in² copper pad). Actual θJA in end equipment will vary based on PCB layout, copper area, and airflow - derating is required above 70°C ambient to maintain TJ ≤ 150°C.
Can TLV2361CDBVTG4 drive a 2-kΩ load while maintaining rail-to-rail output swing?
No - TLV2361CDBVTG4's specified ±2.4 V output swing applies only with RL ≥ 10 kΩ. When driving a 2-kΩ load, the maximum output swing degrades significantly: typical data shows ±1.8 V at ±2.5 V supply and ±1.0 V at ±1.5 V supply. For 2-kΩ loads, consider buffer stages or higher-output-current op-amps like TLV2461. TLV2361CDBVTG4 is optimized for high-impedance interfaces.
Is TLV2361CDBVTG4 RoHS compliant and lead-free?
Yes, TLV2361CDBVTG4 is RoHS compliant and lead-free. Per TI's Packaging Information Addendum, the part uses "NIPDAU | SN" (nickel-palladium-gold over tin-lead-free solderable finish) and carries an MSL Level-1 rating (unlimited floor life at ≤30°C/60% RH). The "G4" suffix in TLV2361CDBVTG4 denotes TI's green packaging standard - confirming halogen-free, lead-free, and RoHS-compliant construction.
