Product details
Overview
TLV2332IPWR from Texas Instruments is a dual-channel, low-voltage, medium-power operational amplifier fabricated in LinCMOS™ technology. It operates from 2 V to 8 V supply, delivers 300 kHz unity-gain bandwidth and 0.38 V/µs slew rate at 3 V, features rail-to-rail output swing down to the negative rail, and targets battery-powered sensor signal conditioning and portable instrumentation.
For engineers reviewing the TLV2332IPWR datasheet, TLV2332IPWR pinout, TLV2332IPWR application, or TLV2332IPWR equivalent, key selection criteria include its 10¹² Ω input impedance, ±30 mA output drive capability, –40°C to 85°C operating range, and TSSOP-8 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2332IPWR uses silicon-gate LinCMOS™ process to achieve ultra-low input bias current (0.6 pA typ at 25°C) and high input impedance, enabling direct interfacing with high-impedance sources like piezoelectric sensors and RC filter networks. Its input common-mode range extends from the negative rail to VDD –1 V, supporting true single-supply operation without level-shifting circuitry.
Internally, the device integrates ESD protection rated to 2000 V (MIL-STD-883C), latch-up immunity, and biasing optimized for stable ac performance across voltage and temperature. The amplifier maintains phase margin ≥39° at unity gain with 20 pF load, ensuring robust stability in unity-gain buffer and active filter configurations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432IDR | Higher quiescent current (1.2 mA vs 0.62 mA), wider VIO range (2.5 mV max), no ESD rating specified | Optimized for higher-speed (2.5 MHz GBW) and higher-drive (60 mA) applications | Select when bandwidth >1 MHz or output current >30 mA is required; avoid if sub-1 mA supply budget is critical |
| LMV358IPWR | Lower VIO (7 mV max), lower supply current (80 µA), but limited CMIR (to VDD –1.3 V) and no rail-to-rail output | Targeted at cost-sensitive, low-power general-purpose use with relaxed input/output swing needs | Select for basic amplification where rail-to-rail output and extended CMIR are not required; verify input common-mode compliance |
Compared with TLV2432IDR and LMV358IPWR, the TLV2332IPWR uniquely balances ultra-low input bias current (0.6 pA), rail-to-rail output, and 300 kHz bandwidth within a 620 µA supply budget - making it optimal for precision, low-voltage, battery-operated sensor interfaces where input impedance and dynamic range are critical.

FAQ
What is the maximum operating temperature range for the TLV2332IPWR?
The TLV2332IPWR is specified for continuous operation from –40°C to +85°C ambient temperature. Its electrical characteristics-including input offset voltage, supply current, and unity-gain bandwidth-are fully characterized across this range, and thermal shutdown is not implemented. Derating of power dissipation per the PW-8 package's 4.2 mW/°C factor is required above 25°C ambient to maintain reliability.
Does the TLV2332IPWR support true rail-to-rail input operation?
The TLV2332IPWR supports rail-to-rail output swing but does not provide full rail-to-rail input. Its common-mode input voltage range extends from the negative rail (GND) up to VDD –1 V at 25°C, and to VDD –1.2 V over the full –40°C to 85°C range. This allows input signals to reach GND but requires that the positive input remain at least 1 V below VDD for guaranteed operation.
Can the TLV2332IPWR drive a 10 nF capacitive load stably?
The TLV2332IPWR maintains ≥39° phase margin when driving a 20 pF capacitive load with 100 kΩ feedback resistance, as verified in the datasheet's Figure 36. Driving 10 nF (10,000 pF) exceeds this by 500× and will cause severe peaking or oscillation. A series resistor (≥100 Ω) must be added between the output and the 10 nF load to isolate the capacitance and restore stability.
What is the typical input offset voltage drift over temperature for TLV2332IPWR?
The TLV2332IPWR has an average temperature coefficient of input offset voltage (αVIO) of 1 µV/°C (typical) over 25°C to 85°C, with a maximum of 1.7 µV/°C. This means that over a 60°C temperature span, VIO typically drifts by ≤60 µV - significantly less than its 9 mV maximum initial offset - making it suitable for applications where calibration occurs only at room temperature.
Is the TLV2332IPWR pin-compatible with other TSSOP-8 dual op amps like the LMV358IPWR?
No, the TLV2332IPWR is not pin-compatible with the LMV358IPWR. While both use TSSOP-8 packages, their pinouts differ: TLV2332IPWR assigns Pin 4 to GND and Pin 8 to VDD, whereas LMV358IPWR uses Pin 4 for V– and Pin 8 for V+. Swapping them without board revision will result in incorrect biasing and functional failure. Always verify pin mapping using official package drawings before substitution.
