Product details
Overview
TL062IPG4 from Texas Instruments is a dual JFET-input operational amplifier optimized for low-power, high-input-impedance signal conditioning in cost-sensitive analog circuits. It delivers 200 µA per amplifier supply current, 3.5 V/µs slew rate, ±11 V common-mode input range (including VCC+), and 1 MHz unity-gain bandwidth - enabling use in battery-powered sensor interfaces and audio preamplifiers.
For engineers reviewing the TL062IPG4 datasheet, TL062IPG4 pinout, TL062IPG4 application, or TL062IPG4 equivalent, key selection criteria include its JFET-input stage (1012 Ω input resistance), rail-to-rail-compatible input voltage range, low 5 pA typical input offset current, and SOIC-8 packaging suitable for space-constrained industrial control modules.
Technical Context
The TL062IPG4 implements a two-stage JFET-input transconductance amplifier architecture with internal frequency compensation, delivering stable unity-gain operation without external components. Its differential pair input stage enables wide common-mode range (VCC– + 4 V to VCC+ – 4 V) and high CMRR (80 dB min).
Designed as a low-power counterpart to the TL072/TL082 families, it maintains comparable AC performance (1 MHz GBW, 3.5 V/µs slew rate) while reducing quiescent current by ~50%. Input bias currents remain temperature-stable below 200 pA at 25°C, supporting precision DC-coupled applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA per amplifier - enables multi-channel operation on 3.3 V or 5 V rails with sub-1 mW per channel dissipation |
| Input Bias Current | 30 pA (typ) - supports high-impedance sensor interfacing (e.g., piezoelectric, pH electrodes) without significant DC error |
| Slew Rate | 3.5 V/µs (typ) - sustains <1% THD for 10 kHz sine waves at ±10 V output swing into 10 kΩ load |
| Unity-Gain Bandwidth | 1 MHz - provides stable closed-loop gain ≥1 with phase margin >60° using standard compensation |
| Input Resistance | 1012 Ω - minimizes loading of high-Z sources such as crystal filters or passive RC networks |
| Common-Mode Range | VCC– + 4 V to VCC+ – 4 V - accepts inputs within 4 V of either rail, simplifying single-supply level-shifting design |
| ESD Rating | 1.5 kV HBM - meets IEC 61000-4-2 Level 2 for robustness in assembly and field environments |
Pinout & Package
TL062IPG4 is packaged in an 8-pin SOIC (Small Outline Integrated Circuit) with 1.27 mm pitch, 4.90 mm × 6.00 mm body size, and gull-wing leads compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to ±10 V swing into 10 kΩ; short-circuit protected |
| 2 | IN– A | Inverting input A - high-impedance JFET node; requires matched trace impedance for noise rejection |
| 3 | IN+ A | Non-inverting input A - accepts common-mode voltages up to VCC+; no internal ESD diodes to rails |
| 4 | VCC– | Negative supply - must be decoupled with 0.1 µF ceramic capacitor placed ≤5 mm from pin |
| 5 | IN+ B | Non-inverting input B - electrically isolated from Channel A; crosstalk attenuation >120 dB at 100 Hz |
| 6 | IN– B | Inverting input B - identical electrical characteristics to Pin 2; shares same die substrate |
| 7 | OUT B | Amplifier B output - independent output stage; supports simultaneous dual-channel signal processing |
| 8 | VCC+ | Positive supply - supplies both amplifiers; thermal coupling ensures matched channel behavior |
Key Features
| Feature | Design Value |
|---|---|
| JFET-input stage | 1012 Ω input resistance enables direct connection to megohm-level sensors without buffer degradation |
| Low power consumption | 200 µA per amplifier allows integration of four independent channels in <1 mA total supply budget |
| Output short-circuit protection | Internally limits current to safe levels during accidental rail shorts, preventing latch-up or thermal runaway |
| Wide common-mode range | Operates with inputs at VCC+, eliminating need for external level shifters in single-supply configurations |
| Internal frequency compensation | Guarantees stability at unity gain without external capacitors - reduces BOM count and layout sensitivity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CDR | Higher supply current (2.8 mA vs 0.4 mA total), 13 V/µs slew rate, tighter VIO spec (3 mV max) | Better for wideband AC-coupled designs requiring faster settling; unsuitable for ultra-low-power battery operation | Select TL072CDR when bandwidth >3 MHz or offset voltage <3 mV is required; avoid if system power budget <1 mA |
| TL082CDR | Higher input bias current (1.2 nA typ), 13 V/µs slew rate, no input offset null pins | Optimized for general-purpose audio and video signal paths where cost and speed outweigh ultra-low input current needs | Choose TL082CDR for legacy designs needing pin compatibility with older TL08x-based boards; verify input current impact on sensor accuracy |
Compared with TL072CDR and TL082CDR, the TL062IPG4 trades bandwidth and slew rate for 93% lower supply current and 24× lower input bias current - making it the only viable option for always-on sensor nodes and energy-harvesting systems where µA-level quiescent operation is mandatory.

FAQ
What is the maximum operating temperature range for TL062IPG4?
The TL062IPG4 is rated for operation from –40°C to +85°C ambient temperature, matching the TL062I grade specification. This range supports deployment in industrial control cabinets, automotive cabin electronics, and consumer appliances without derating. The device maintains full electrical performance across this range, including 200 µA supply current and 1 MHz unity-gain bandwidth at 85°C.
Does TL062IPG4 require external compensation capacitors?
No, TL062IPG4 features internal frequency compensation optimized for unity-gain stability. It operates reliably with closed-loop gains ≥1 without external capacitors, reducing bill-of-materials count and layout complexity. This design eliminates phase-margin tuning requirements seen in decompensated op-amps like the TL072, simplifying design validation for first-pass success.
Can TL062IPG4 be used in single-supply configurations?
Yes, TL062IPG4 supports single-supply operation with inputs extending to VCC+. Its common-mode input range spans VCC– + 4 V to VCC+ – 4 V, allowing use with 5 V or 3.3 V rails when VCC– = GND. For rail-to-rail output, external level-shifting or output clamping may be needed since output swing is limited to ±10 V under ±15 V supplies.
What is the input offset voltage specification for TL062IPG4?
The TL062IPG4 has a maximum input offset voltage of 6 mV at 25°C and 9 mV across the full –40°C to +85°C range. This value is specified per amplifier channel and remains stable over time due to JFET-input construction. For applications requiring tighter offset control, the TL062IPG4 includes no dedicated offset-null pins - external trimming via feedback networks is recommended.
How does TL062IPG4 compare to TL062CP in terms of package and performance?
TL062IPG4 uses SOIC-8 packaging (4.90 mm × 6.00 mm) with gull-wing leads, while TL062CP uses PDIP-8 (9.59 mm × 7.94 mm) with through-hole leads. Electrically, both share identical specifications: 200 µA supply current, 3.5 V/µs slew rate, and 1 MHz bandwidth. The TL062IPG4 variant is optimized for surface-mount assembly and automated optical inspection in high-volume production.
