Product details
Overview
TLV2361IDBVR 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 noise, and operates across −40°C to +85°C. It enables high-fidelity signal conditioning in battery-powered audio and sensor front-ends.
For engineers reviewing the TLV2361IDBVR datasheet, TLV2361IDBVR pinout, TLV2361IDBVR application, or TLV2361IDBVR equivalent, key selection criteria include low-voltage rail-to-rail output capability, bipolar process stability at sub-2V supply, thermal performance in SOT-23 (θJA = 206°C/W), and compatibility with space-constrained portable instrumentation designs.
Technical Context
The TLV2361IDBVR uses a proprietary Texas Instruments bipolar process optimized for low-voltage operation without sacrificing bandwidth or output drive. Its architecture maintains stable phase margin under capacitive loads up to 100 pF while delivering 60–80 dB large-signal voltage gain and 85 dB CMRR at ±2.5 V supply.
It supports true dual-supply operation down to ±1 V, with input common-mode range extending to ±1.4 V and output swing within 100 mV of each rail at 10 kΩ load. The device does not feature rail-to-rail input; its input stage is optimized for precision DC-coupled amplification rather than wide common-mode tracking.

FAQ
What is the minimum supply voltage required for stable operation of the TLV2361IDBVR?
The TLV2361IDBVR is specified for stable operation down to ±1 V dual supply (2 V total). At this voltage, it maintains functional bandwidth (>1 MHz), usable output swing (±0.8 V), and input common-mode range. Operation below ±1 V is not characterized and may result in degraded gain, increased distortion, or failure to meet datasheet specifications. Always verify performance in final circuit conditions using TI's SPICE models.
Does the TLV2361IDBVR support rail-to-rail input operation?
No, the TLV2361IDBVR does not support rail-to-rail input. Its input common-mode voltage range is limited to ±1.4 V at ±2.5 V supply and ±0.5 V at ±1.5 V supply. Input signals exceeding these limits cause phase reversal or clipping. For true rail-to-rail input capability, consider alternatives like the TLV2461IDBVR. The TLV2361IDBVR's strength lies in rail-to-rail *output* swing and low-voltage bipolar precision-not input range.
What is the thermal performance of the TLV2361IDBVR in SOT-23-5 package?
The TLV2361IDBVR in SOT-23-5 (DBV) package has a junction-to-ambient thermal resistance (θJA) of 206°C/W, measured per JEDEC JESD 51-7. With a maximum junction temperature of 150°C and ambient temperature of 85°C, the maximum allowable power dissipation is approximately 317 mW. Layout best practices-including copper pour under pin 4 (VCC−) and thermal vias-can improve heat transfer. Derate linearly above 85°C ambient.
Can the TLV2361IDBVR drive capacitive loads directly?
The TLV2361IDBVR is characterized for stability with up to 100 pF capacitive load when driving into 10 kΩ, per typical operating conditions. Driving larger capacitive loads (e.g., >200 pF) without isolation resistance may cause peaking or oscillation. For ADC input driving or cable termination, add a 10–50 Ω series resistor between TLV2361IDBVR output and the capacitive load to maintain phase margin. Do not rely on internal compensation for heavy capacitive loading.
How does the TLV2361IDBVR compare to the dual-channel TLV2362 in terms of electrical performance?
The TLV2361IDBVR and TLV2362 share identical per-amplifier specifications: same bandwidth (7 MHz), slew rate (3 V/µs), noise (8 nV/√Hz), and supply range (±1 V to ±2.5 V). Differences are purely in channel count and package-TLV2361IDBVR is single-channel in SOT-23-5, while TLV2362 variants occupy 8-pin packages (SOIC, VSSOP, TSSOP). Pin compatibility does not exist between them; TLV2361IDBVR cannot substitute for one channel of TLV2362 without PCB redesign.
