Product details
Overview
TL33071D from Texas Instruments is a single-channel, bipolar-input operational amplifier designed for industrial and vehicular applications requiring wide temperature operation (−40°C to 105°C), rail-to-rail input capability down to VCC− (ground in single-supply mode), 4.5 MHz gain-bandwidth product, 13 V/µs slew rate, and low 3 mV max input offset voltage (A-suffix grade). It delivers large output swing (−14.7 V to 14 V with ±15-V supplies) and drives up to 10,000 pF capacitive loads.
For engineers reviewing the TL33071D datasheet, TL33071D pinout, TL33071D application, or TL33071D equivalent, this device is selected for precision signal conditioning in automotive sensor interfaces, industrial process control analog front-ends, and high-stability single-supply instrumentation where input common-mode range including ground and robust output drive are critical.
Technical Context
The TL33071D employs a Darlington transistor input stage delivering high input resistance (150 MΩ), low input bias current (−0.7 µA typ), and low input offset voltage. Its all-NPN output stage eliminates crossover distortion and enables symmetrical source/sink AC response with excellent phase margin (60°) and gain margin (12 dB) at unity gain.
It supports true single-supply operation from 4 V to 44 V total supply range (e.g., 5 V or ±15 V), features internal offset null pins (OFFSET N1/N2), and includes output short-circuit protection with unlimited duration at ≤25°C. Input common-mode range extends to VCC−, enabling direct sensing of ground-referenced signals.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL34071D | Same architecture but rated only for 0°C to 70°C; lower max input offset voltage (1.5 mV) in standard grade. | Restricted to commercial-temperature environments (e.g., office equipment, consumer test gear); not qualified for under-hood or factory-floor use. | Select TL34071D only if ambient temperature remains within 0–70°C and tighter initial offset is prioritized over thermal stability. |
| MC33071DR2G | Pin-compatible ON Semiconductor variant; identical electrical specs but different qualification testing and packaging traceability. | Used in legacy designs where second-source procurement is mandated; same functional behavior in circuit but distinct lot traceability and reliability reporting. | Choose MC33071DR2G when dual-sourcing is contractually required or TI supply continuity is constrained. |
Compared with TL34071D, TL33071D provides guaranteed performance over −40°C to 105°C and higher input offset voltage tolerance (3 mV vs. 1.5 mV), while MC33071DR2G offers identical functionality with alternate supply-chain validation-making TL33071D optimal for new industrial/automotive designs demanding extended temperature assurance.

FAQ
What is the operating temperature range specified for TL33071D?
The TL33071D is specified for industrial/vehicular operation from −40°C to 105°C. This range is validated per the datasheet's recommended operating conditions and absolute maximum ratings, making it suitable for under-hood automotive electronics, factory automation controllers, and outdoor environmental monitoring systems where thermal stress exceeds commercial-grade limits. The TL33071D maintains its key parameters-including input offset voltage, gain-bandwidth, and slew rate-within published limits across this full span.
Does TL33071D support true single-supply operation with input referenced to ground?
Yes, TL33071D supports true single-supply operation with input common-mode voltage range extending to VCC− (pin 4), which is ground in single-supply configurations. This allows direct connection of ground-referenced sensors-such as thermistors, strain gauges, or current-sense shunts-without external level-shifting circuitry. The datasheet confirms VICR includes 0 V at VCC = 5 V and −15 V to 12.8 V at ±15 V supplies, confirming rail-to-rail input capability down to the negative rail.
What package type is TL33071D supplied in, and is it RoHS-compliant?
TL33071D is supplied in an 8-pin SOIC (D package), gull-wing surface-mount format. Per Texas Instruments' official packaging documentation, TL33071D carries RoHS-compliant lead finish (NIPDAU) and meets JEDEC standards for moisture sensitivity level (MSL) and peak reflow profile. Tape-and-reel ordering is supported via suffix "R" (e.g., TL33071DR), enabling automated PCB assembly without lead-free compatibility concerns.
Can TL33071D drive heavy capacitive loads without oscillation?
Yes, TL33071D is characterized for stable operation with up to 10,000 pF capacitive load, as confirmed in the datasheet's operating characteristics table. Its all-NPN output stage and internal compensation deliver 60° phase margin with no load and maintain 40° phase margin even with 300 pF load-enabling direct interface to ADC inputs, piezoelectric elements, and long transmission lines without external series resistors or isolation networks.
How does TL33071D differ from TL34071D in terms of performance and qualification?
TL33071D and TL34071D share identical electrical architecture and pinout but differ in temperature qualification: TL33071D is rated for −40°C to 105°C (industrial/vehicular), while TL34071D is limited to 0°C to 70°C (commercial). TL33071D also specifies higher max input offset voltage (3 mV vs. 1.5 mV for TL34071D standard grade) due to wider thermal drift allowance-but both meet 0.02% THD and 4.5 MHz GBW. TL33071D undergoes extended reliability testing per AEC-Q100 stress profiles for automotive use.
