Texas Instruments TLV2361IDBV

Overview

TLV2361IDBV from Texas Instruments is a single-channel, high-performance, low-voltage operational amplifier in a 5-pin SOT-23 package. It operates from ±1 V to ±2.5 V supply rails, delivers 7 MHz unity-gain bandwidth and 3 V/µs slew rate at ±2.5 V, and achieves ±2.4 V output swing into 10 kΩ - enabling precision signal conditioning in battery-powered audio and sensor interfaces.

For engineers reviewing the TLV2361IDBV datasheet, TLV2361IDBV pinout, TLV2361IDBV application, or TLV2361IDBV equivalent, key selection criteria include its rail-to-rail input common-mode range (±1.4 V at full temperature), low 8 nV/√Hz input noise at 1 kHz, and guaranteed operation across −40°C to +85°C industrial temperature range.

Technical Context

The TLV2361IDBV uses a proprietary Texas Instruments bipolar process optimized for low-voltage operation without sacrificing speed or linearity. Its architecture supports stable unity-gain configuration with 7 MHz bandwidth and maintains >60 dB large-signal voltage gain up to ±1 V output swing.

It features internally compensated frequency response, differential input stage with ±1.4 V common-mode input voltage range at full temperature, and output stage capable of sourcing/sinking ≥20 mA while delivering ±2.4 V swing into 10 kΩ load at ±2.5 V supplies.

FAQ

What is the maximum supply voltage for TLV2361IDBV?

The absolute maximum supply voltage for TLV2361IDBV is ±3.5 V, but the recommended operating range is ±1 V to ±2.5 V. Exceeding ±2.5 V may degrade performance or reliability; operation at ±3.5 V is strictly limited to short-duration stress conditions and not for continuous use. The TLV2361IDBV is optimized for low-voltage systems, and its specifications - including 7 MHz bandwidth and ±2.4 V output swing - are guaranteed only within the ±1 V to ±2.5 V range.

Does TLV2361IDBV support rail-to-rail input or output?

TLV2361IDBV supports rail-to-rail input common-mode range up to ±1.4 V relative to the supply midpoint, but it does not achieve true rail-to-rail output. Its output swings to ±2.4 V into 10 kΩ at ±2.5 V supplies, leaving ~100 mV headroom to each rail. This is sufficient for most 12-bit ADC interfaces and audio line drivers, but not for applications requiring output within 20 mV of either supply rail. The TLV2361IDBV datasheet specifies this behavior explicitly under "Maximum Positive/Negative Peak Output Voltage".

What is the thermal resistance (θJA) of TLV2361IDBV in SOT-23 package?

The junction-to-ambient thermal resistance (θJA) of TLV2361IDBV 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 (1-layer copper, 1 in² pad). Real-world PCB layout with added copper pour or thermal vias can reduce effective θJA significantly - typical designs achieve 120–160°C/W. The TLV2361IDBV's maximum virtual junction temperature is 150°C, so at 2.5 mA supply current and ±2.5 V supply, power dissipation is ~12.5 mW, resulting in ~2.6°C rise above ambient under standard conditions.

Can TLV2361IDBV drive capacitive loads directly?

TLV2361IDBV is not unity-gain stable with heavy capacitive loads (>100 pF) without isolation resistance. The datasheet recommends adding a 10–100 Ω series resistor between the output and capacitive load to maintain phase margin. For example, driving a 1 nF ADC input capacitor requires ≥50 Ω series resistance to prevent peaking or oscillation. This limitation arises from its internal compensation optimized for resistive loads; the TLV2361IDBV's 7 MHz bandwidth and 3 V/µs slew rate make it sensitive to capacitive loading effects, and stability must be verified per application.

Is TLV2361IDBV pin-compatible with other SOT-23 op-amps like MCP6001 or LMV321?

No, TLV2361IDBV is not pin-compatible with MCP6001 or LMV321. While all three use SOT-23-5 packages, their pinouts differ: TLV2361IDBV uses OUT/IN−/VCC−/IN+/VCC+, whereas MCP6001 uses VDD/IN+/IN−/OUT/GND and LMV321 uses VDD/IN+/IN−/OUT/GND. Swapping them without PCB revision will cause incorrect biasing or no function. The TLV2361IDBV's unique pin assignment - especially VCC− on Pin 3 instead of GND - is critical for bipolar supply operation and must be matched in layout.
