Product details
Overview
TLV2362IPSR from Texas Instruments is a dual, low-voltage operational amplifier optimized for ±1 V to ±2.5 V supply operation, delivering 7 MHz unity-gain bandwidth, 3 V/µs slew rate, ±2.4 V output swing (at ±2.5 V), 8 nV/√Hz input noise, and 85 dB CMRR - enabling high-fidelity signal conditioning in battery-powered audio and sensor front-ends.
For engineers reviewing the TLV2362IPSR datasheet, TLV2362IPSR pinout, TLV2362IPSR application, or TLV2362IPSR equivalent, key selection criteria include rail-to-rail output capability at sub-3V supplies, thermal performance in TSSOP-8 (θJA = 149°C/W), low distortion (0.004% THD+N at 3 kHz), and compatibility with single-supply or split-supply configurations in portable instrumentation.
Technical Context
The TLV2362IPSR implements a bipolar input stage with JFET-enhanced biasing to achieve stable operation down to ±1 V supply while maintaining wide common-mode input range (±1.4 V) and high open-loop gain (60 dB). Its internal compensation ensures unity-gain stability without external components across capacitive loads up to 100 pF.
Designed for low-noise analog signal chains, it features matched transistor pairs and precision resistor networks (11 resistors, 46 transistors per device) to minimize offset drift (7.5 mV max over temperature) and maintain CMRR > 75 dB across −40°C to +85°C operating range.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2372IDR | Higher supply current (2.9 mA/ch), lower noise (7 nV/√Hz), same TSSOP-8 package. | Better suited for ultra-low-noise sensor interfaces where power budget allows +0.4 mA/ch. | Select TLV2372IDR if noise floor is critical and supply headroom permits higher ICC. |
| OPA2340UA | Rail-to-rail input/output, 10 MHz GBW, but requires ≥2.7 V supply; SO-8 package only. | Not usable below 2.7 V; incompatible with ±1 V or 1.8 V systems where TLV2362IPSR operates. | Choose OPA2340UA only for 3 V+ designs requiring full rail-to-rail input and wider bandwidth. |
Compared with TLV2362IPSR, TLV2372IDR trades marginal noise improvement for increased quiescent current, while OPA2340UA offers broader input range at the cost of minimum supply voltage compliance - making TLV2362IPSR uniquely suitable for sub-2 V dual-amplifier applications.

FAQ
What is the minimum supply voltage required for guaranteed operation of the TLV2362IPSR?
The TLV2362IPSR is specified for guaranteed operation down to ±1 V supply (i.e., total supply span of 2 V), with full functionality including input common-mode range, output swing, and bandwidth maintained across this range per the datasheet's recommended operating conditions.
Does the TLV2362IPSR support rail-to-rail input operation?
No, the TLV2362IPSR does not support 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 - meaning inputs must remain within those bounds relative to the supply rails to avoid phase reversal or degraded performance.
What is the thermal resistance (θJA) of the TLV2362IPSR in its TSSOP-8 package?
The TLV2362IPSR in TSSOP-8 (PW) package has a junction-to-ambient thermal resistance (θJA) of 149°C/W, measured per JEDEC JESD 51-7 on a standard 2-layer board with 1 in² copper area, as documented in the Absolute Maximum Ratings table of the SLOS195H datasheet.
Can the TLV2362IPSR drive capacitive loads without oscillation?
Yes, the TLV2362IPSR is internally compensated for unity-gain stability with capacitive loads up to 100 pF, as verified in the Operating Characteristics section (test condition: RL = 10 kΩ, CL = 100 pF). For loads >100 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended.
Is the TLV2362IPSR pin-compatible with other dual op-amps in TSSOP-8 packages?
No, the TLV2362IPSR uses a non-standard pinout for dual op-amps: Pins 1/8 are outputs, Pins 2/7 are inverting inputs, Pins 3/6 are non-inverting inputs, and Pins 4/5 are supply rails. This differs from industry-standard dual-op-amp pinouts (e.g., SOIC-8), so PCB layout must follow the TLV2362-specific mapping shown in the datasheet.
