Product details
Overview
TLV2361IDBVRG4 from Texas Instruments is a single-channel, low-voltage, high-performance 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 noise, and operates across −40°C to +85°C. It is used in portable audio signal conditioning where rail-to-rail output swing and low-noise amplification are critical.
For engineers reviewing the TLV2361IDBVRG4 datasheet, TLV2361IDBVRG4 pinout, TLV2361IDBVRG4 application, or TLV2361IDBVRG4 equivalent, key selection considerations include its guaranteed operation down to ±1 V supply, wide common-mode input range (±1.4 V at full temperature range), low quiescent current (2.5 mA max per amplifier), and compatibility with space-constrained battery-powered systems requiring high dynamic range.
Technical Context
The TLV2361IDBVRG4 employs a proprietary bipolar process optimized for low-voltage precision amplification. Its architecture supports stable operation with capacitive loads up to 100 pF while maintaining 60–80 dB large-signal voltage gain and 85 dB CMRR at 25°C - enabling accurate DC-coupled sensor interfacing and AC-coupled audio paths without external compensation.
It features internally compensated unity-gain stability, rail-to-rail output stage capable of sourcing/sinking ≥10 mA, and input bias currents below 150 nA over full temperature range. The device does not include shutdown or rail-to-rail input capability, distinguishing it from later-generation TI op-amps like the TLV9001.
Key Specifications

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 |
|---|---|---|---|
| TLV2371IDBVR | Higher supply voltage range (±1.4 V to ±8 V), lower input bias current (1 pA typ), but only 3 MHz bandwidth and 1.7 V/µs slew rate. | Better for high-impedance pH or ion-selective electrodes; insufficient for audio-band amplification requiring >5 MHz BW. | Select TLV2371IDBVR when ultra-low input bias dominates over speed and noise requirements. |
| OPA333AIDBVR | Zero-drift architecture, 10 µV max VOS, 0.1 µV/°C drift, but limited to ±1.8 V max supply and 350 kHz bandwidth. | Ideal for precision DC-coupled thermocouple or RTD interfaces; cannot support audio or fast transient signals. | Select OPA333AIDBVR when microvolt-level DC accuracy and near-zero drift outweigh bandwidth needs. |
Compared with TLV2361IDBVRG4, TLV2371IDBVR trades bandwidth and slew rate for wider supply flexibility and femtoampere input bias, while OPA333AIDBVR sacrifices speed and supply range to achieve nanovolt-level offset stability - making TLV2361IDBVRG4 the optimal balance for mixed-signal audio and low-voltage sensor front-ends demanding both speed and noise performance.

FAQ
What is the minimum supply voltage required for reliable operation of the TLV2361IDBVRG4?
The TLV2361IDBVRG4 is specified to operate reliably down to ±1 V supply voltage (i.e., total supply span of 2 V). At this minimum, it maintains functional output swing, albeit reduced to ±0.8 V typical. Full performance - including 7 MHz bandwidth and ±2.4 V swing - is guaranteed at ±2.5 V. Operation below ±1 V is not characterized and may result in undefined behavior or latch-up.
Does the TLV2361IDBVRG4 support rail-to-rail input operation?
No, the TLV2361IDBVRG4 does not feature rail-to-rail input capability. Its common-mode input voltage range is specified as ±1.4 V maximum over the full −40°C to +85°C temperature range, referenced to the midpoint between VCC+ and VCC−. This means with ±2.5 V supplies, inputs must remain within ±1.4 V of ground (i.e., −1.4 V to +1.4 V), excluding the supply rails themselves.
Can the TLV2361IDBVRG4 drive a 100 pF capacitive load without oscillation?
Yes, the TLV2361IDBVRG4 is internally compensated and characterized to remain stable driving up to 100 pF capacitive loads under standard test conditions (AV = 40, RL = 10 kΩ). This eliminates the need for external isolation resistors in most audio and sensor interface applications, simplifying layout and reducing component count compared to uncompensated op-amps.
What is the maximum output current capability of the TLV2361IDBVRG4?
The absolute maximum output current rating for the TLV2361IDBVRG4 is ±20 mA, as defined in the Absolute Maximum Ratings table. However, the device is characterized to deliver ±10 mA while maintaining ±2.4 V output swing into 10 kΩ at ±2.5 V supplies. Sustained output currents above ±10 mA will reduce output voltage swing and increase junction temperature, requiring thermal derating per θJA = 206°C/W.
Is the TLV2361IDBVRG4 pin-compatible with other SOT-23-5 op-amps like the TLV271 or MCP6001?
No, the TLV2361IDBVRG4 uses a non-standard pinout for SOT-23-5: Pin 1 = OUT, Pin 2 = IN−, Pin 3 = IN+, Pin 4 = VCC−, Pin 5 = VCC+. This differs from industry-standard configurations (e.g., TLV271: Pin 1 = SHDN, Pin 2 = IN−, Pin 3 = IN+, Pin 4 = V−, Pin 5 = OUT). Direct replacement requires PCB redesign - no pin-compatible alternatives exist in the same package.
