Product details
Overview
TL061IPG4 from Texas Instruments is a single-channel, low-power JFET-input operational amplifier designed for precision analog signal conditioning in cost-sensitive industrial and consumer systems. It delivers 200 µA typical supply current, 3.5 V/µs slew rate, ±11 V common-mode input range (including VCC+), and 1012 Ω input resistance - enabling high-impedance sensor interfacing in battery-powered tablets and white goods.
For engineers reviewing the TL061IPG4 datasheet, TL061IPG4 pinout, TL061IPG4 application, or TL061IPG4 equivalent, key selection criteria include its JFET-input architecture for ultra-low bias current (30 pA typ), wide –55°C to 125°C operating temperature range (I-grade), and SOIC-8 package compatibility with legacy TL071/TL081 layouts while reducing power by >50%.
Technical Context
The TL061IPG4 implements a fully differential JFET-input stage followed by a high-gain CMOS output stage, supporting rail-to-rail output swing within ±10 V under 10 kΩ load. Its internal frequency compensation ensures unity-gain stability without external components, and latch-up-free operation meets MIL-PRF-38535 requirements for rugged environments.
It features integrated EMI/RF filters and 1.5 kV HBM ESD protection, with common-mode input voltage extending to VCC+ - enabling direct sensing of signals referenced to the positive rail. The device operates from ±5 V to ±15 V dual supplies and provides output short-circuit protection across its full temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071CP | Higher supply current (2.8 mA vs 0.2 mA), faster slew rate (13 V/µs), lower input noise (18 nV/√Hz). | Preferred where speed and SNR outweigh power constraints - e.g., audio preamps, not battery-powered sensors. | Select TL071CP only when bandwidth >3 MHz and noise <20 nV/√Hz are mandatory; avoid in energy-harvesting or always-on systems. |
| OPA140AIDBVR | FET-input, rail-to-rail output, 1.8 pA bias current, 5.5 V/µs slew rate, 12 V max supply - requires single-supply design adaptation. | Better for ultra-high-precision, low-noise, low-voltage (<12 V) applications - e.g., medical sensor nodes. | Choose OPA140AIDBVR when sub-picoampere bias and RRO are essential; TL061IPG4 remains optimal for dual-supply, cost-driven industrial use. |
Compared with TL071CP and OPA140AIDBVR, TL061IPG4 uniquely balances ultra-low power (200 µA), JFET-input integrity, and dual-supply flexibility - making it the most suitable choice for legacy-compatible, thermally constrained, and cost-sensitive embedded analog stages.

FAQ
What is the maximum supply voltage rating for TL061IPG4?
The TL061IPG4 has an absolute maximum supply voltage rating of ±18 V (36 V total). However, its recommended operating range is ±5 V to ±15 V. Operating beyond ±15 V risks exceeding power dissipation limits and degrading long-term reliability - always verify thermal design when approaching absolute max ratings. TL061IPG4 must never be operated with asymmetric supplies exceeding these limits.
Does TL061IPG4 support rail-to-rail input or output?
TL061IPG4 supports rail-to-rail output swing (±10 V into 10 kΩ with ±15 V supplies) but does not feature rail-to-rail input. Its common-mode input range extends from VCC– + 4 V to VCC+ – 4 V - meaning it accepts inputs up to 4 V below VCC+. This "VCC+-inclusive" behavior allows inputs referenced to the positive rail, but true rail-to-rail input requires dedicated RRI op amps. TL061IPG4's input stage is JFET-based, not CMOS.
Can TL061IPG4 replace TL071CP in existing designs?
TL061IPG4 can often replace TL071CP in non-speed-critical applications due to identical pinout and SOIC-8 packaging, but with critical trade-offs: 14× lower supply current (200 µA vs 2.8 mA), 3× slower slew rate (3.5 vs 13 V/µs), and higher input noise (30 vs 18 nV/√Hz). TL061IPG4 is suitable for DC/low-frequency signal conditioning; TL071CP remains necessary for audio or wideband applications. Verify loop stability and bandwidth margins before substitution.
What is the input offset voltage specification for TL061IPG4?
TL061IPG4 (I-grade) specifies a maximum input offset voltage of 9 mV over its full operating temperature range (–40°C to +85°C), with a typical value of 3 mV at 25°C. Its temperature coefficient is 10 µV/°C - meaning offset drift contributes ≤1.2 mV over a 120°C span. This performance suits medium-precision applications like motor current sensing or temperature transmitter front-ends, but not sub-100 µV metrology-grade systems.
Is TL061IPG4 suitable for single-supply operation?
TL061IPG4 is specified for dual-supply operation (±5 V to ±15 V) and is not characterized for true single-supply use. While it can function with VCC– = 0 V and VCC+ = +15 V, its common-mode input range then becomes 4 V to 11 V - excluding ground-referenced signals. Output swing also degrades near 0 V. For robust single-supply designs, TI recommends alternatives like TLV2461 or OPA344. TL061IPG4 should only be used in single-rail configurations with careful biasing and validation.
