Product details
Overview
TLV2361IDBVTE4 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, ±2.4 V output swing (at ±2.5 V supplies), and 8 nV/√Hz input noise at 1 kHz - enabling high-fidelity signal conditioning in battery-powered audio and sensor front-ends.
For engineers reviewing the TLV2361IDBVTE4 datasheet, TLV2361IDBVTE4 pinout, TLV2361IDBVTE4 application, or TLV2361IDBVTE4 equivalent, key selection criteria include low-voltage operation down to ±1 V, wide output voltage swing, low-noise performance, and compatibility with space-constrained PCB layouts using the 5-pin SOT-23 footprint.
Technical Context
The TLV2361IDBVTE4 employs a proprietary bipolar process optimized for low-voltage linearity and dynamic range. Its architecture supports stable operation with capacitive loads up to 100 pF while maintaining 60–80 dB large-signal differential voltage amplification and 85 dB common-mode rejection at ±2.5 V supply.
It features internally compensated unity-gain stability, operates across −40°C to +85°C, and exhibits supply-voltage rejection of 80 dB - making it suitable for mixed-signal systems where power rail noise must be rejected without external compensation components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2371IDBVR | Higher quiescent current (2.5 mA vs 2.25 mA typ), lower noise (7 nV/√Hz), same SOT-23-5 package | Better suited for ultra-low-noise audio paths; less optimal for battery lifetime-critical logging | Select TLV2371IDBVR when noise floor dominates over power budget |
| OPA316IDBVR | Wider bandwidth (10 MHz), higher slew rate (6 V/µs), but requires ≥1.8 V supply (not ±1 V) | Enables higher-frequency sensor interfaces but incompatible with sub-1.8 V battery rails | Select OPA316IDBVR only if supply ≥±1.8 V and bandwidth >7 MHz is required |
Compared with TLV2361IDBVTE4, TLV2371IDBVR trades marginal noise improvement for identical low-voltage capability, while OPA316IDBVR offers superior speed at the cost of minimum supply voltage compliance - making TLV2361IDBVTE4 the sole choice for ±1 V operation with balanced noise, speed, and output swing.

FAQ
What is the minimum supply voltage required for TLV2361IDBVTE4 to operate within specifications?
The TLV2361IDBVTE4 is specified to operate with a minimum supply voltage of ±1 V (i.e., total supply span of 2 V). At this voltage, it maintains functional output swing, bandwidth, and input common-mode range per the datasheet's recommended operating conditions. Operation below ±1 V may result in degraded gain, reduced output swing, or failure to meet slew rate or noise specifications.
Does TLV2361IDBVTE4 support rail-to-rail input operation?
No, TLV2361IDBVTE4 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 - referenced to the midpoint between VCC+ and VCC−. Input signals must remain within these bounds to avoid phase reversal or increased offset error.
Can TLV2361IDBVTE4 drive a 10 kΩ load while maintaining its full output voltage swing?
Yes, TLV2361IDBVTE4 delivers ±2.4 V typical output swing into a 10 kΩ load at ±2.5 V supply, as confirmed in the Electrical Characteristics table. This represents >95% of the theoretical rail-to-rail range and is validated across temperature and process corners - making it suitable for driving standard ADC reference buffers and line-level audio loads.
What is the thermal resistance (θJA) of the TLV2361IDBVTE4 in its SOT-23-5 package?
The junction-to-ambient thermal resistance (θJA) for TLV2361IDBVTE4 in the SOT-23-5 (DBV) package is 206°C/W, as specified in the Absolute Maximum Ratings table. This value assumes standard JEDEC test board conditions (2S2P layout); actual θJA in end-equipment will vary based on PCB copper area, airflow, and nearby heat sources.
Is TLV2361IDBVTE4 pin-compatible with other members of the TLV236x family?
Yes, TLV2361IDBVTE4 shares identical pinout and footprint with all TLV2361 variants in SOT-23-5 (e.g., TLV2361CDBVR, TLV2361IDBVR), including matching OUT, IN−, IN+, VCC−, and VCC+ assignments. However, it is not pin-compatible with TLV2362 dual-amplifier variants, which use 8-pin packages and different pin mapping.
