Product details
Overview
TLV2361IDBVT 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 operates across −40°C to +85°C. It is used in portable audio signal conditioning where rail-to-rail output swing and low-noise performance are critical.
For engineers reviewing the TLV2361IDBVT datasheet, TLV2361IDBVT pinout, TLV2361IDBVT application, or TLV2361IDBVT equivalent, this page provides verified specifications, validated pin functions, real-world use cases in battery-powered analog front-ends, and confirmed alternative parts with documented functional and packaging differences.
Technical Context
The TLV2361IDBVT employs a bipolar process optimized for low-voltage operation, enabling stable amplification down to ±1 V supply while maintaining wide output voltage swing and high dynamic range. Its architecture supports rail-to-rail output drive into 10 kΩ loads and achieves 85 dB common-mode rejection at ±0.5 V common-mode input.
It features internal compensation for unity-gain stability, operates with input common-mode voltage up to ±1.4 V (at ±2.5 V supplies), and maintains 60–80 dB large-signal differential voltage gain across temperature. The device is not rail-to-rail input but supports full-scale input within its specified common-mode range.

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 |
|---|---|---|---|
| TLV2371IDBVT | Higher supply voltage range (±1.4 V to ±8 V), 3 MHz bandwidth, 1.7 V/µs slew rate, 17 nV/√Hz noise. | Less suitable for sub-±1.5 V systems; better for mixed-signal rails with higher headroom. | Choose TLV2371IDBVT when wider supply flexibility and lower quiescent current (570 µA vs 2.5 mA) outweigh noise and speed requirements. |
| OPA316IDBVT | Rail-to-rail input/output, 10 MHz bandwidth, 6 V/µs slew rate, 11 nV/√Hz noise, ±1.7 V to ±5.5 V supply. | Superior input stage enables true DC-coupled sensor interfaces; higher power consumption (650 µA per channel). | Choose OPA316IDBVT when rail-to-rail input capability is mandatory for zero-V common-mode designs, e.g., single-supply transducer bridges. |
Compared with TLV2361IDBVT, TLV2371IDBVT trades bandwidth and noise for lower power and broader supply range, while OPA316IDBVT adds rail-to-rail input at higher cost and current draw-making TLV2361IDBVT optimal for fixed ±1.5 V/±2.5 V audio and industrial analog front-ends demanding best-in-class noise/speed balance.

FAQ
What is the minimum supply voltage for reliable operation of the TLV2361IDBVT?
The TLV2361IDBVT is specified for reliable operation down to ±1 V supply (2 V total). At this level, it maintains functional output swing and stability per datasheet Section 6.2. Operation below ±1 V is not characterized and may result in reduced gain, increased distortion, or failure to meet slew rate or bandwidth specs. Always verify performance under actual load and temperature conditions in final design.
Does the TLV2361IDBVT support rail-to-rail input operation?
No, the TLV2361IDBVT does not support rail-to-rail input. Its common-mode input voltage range is specified as ±1.4 V at ±2.5 V supply (Section 4, Table 1), meaning inputs must remain within 1.1 V of each rail. For true rail-to-rail input capability, consider alternatives like OPA316IDBVT. The TLV2361IDBVT does provide rail-to-rail output swing into 10 kΩ loads.
What is the thermal resistance (θJA) of the TLV2361IDBVT in its SOT-23-5 package?
The TLV2361IDBVT in SOT-23-5 (DBV) package has a junction-to-ambient thermal resistance (θJA) of 206°C/W, as stated in the Absolute Maximum Ratings table (Section 3). This value assumes standard JEDEC test board conditions (2-layer board, 1 in² copper pad). Actual θJA in end equipment depends on PCB layout, copper area, airflow, and nearby heat sources.
Can the TLV2361IDBVT drive capacitive loads directly?
The TLV2361IDBVT is unity-gain stable but not optimized for heavy capacitive loads. Driving >100 pF directly may cause peaking or oscillation. For loads exceeding 100 pF, add a small series resistor (10–50 Ω) between the output and capacitance, or use a dedicated buffer stage. Refer to Figure 5 in the datasheet for frequency-dependent output swing limitations under capacitive loading.
Is the TLV2361IDBVT pin-compatible with other SOT-23-5 op-amps like the TLV2371IDBVT?
Yes, the TLV2361IDBVT and TLV2371IDBVT share identical SOT-23-5 (DBV) pinout: Pin 1 = OUT, Pin 2 = IN−, Pin 3 = IN+, Pin 4 = VCC−, Pin 5 = VCC+. However, they are not functionally interchangeable without circuit review due to differences in bandwidth (7 MHz vs 3 MHz), noise (8 nV/√Hz vs 17 nV/√Hz), and supply range (±1 V min vs ±1.4 V min). Layout reuse is possible; electrical validation is required.
