Product details
Overview
TL062ID from Texas Instruments is a dual JFET-input operational amplifier designed 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 typical slew rate, and ±11 V common-mode input range extending to VCC+, enabling use in rail-to-rail input-capable front-end stages of battery-powered instrumentation and audio preamplifiers.
For engineers reviewing the TL062ID datasheet, TL062ID pinout, TL062ID application, or TL062ID equivalent, key selection criteria include ultra-low quiescent current, JFET-input bias current below 200 pA at 25°C, unity-gain bandwidth of 1 MHz, input offset voltage ≤15 mV, and SOIC-8 package compatibility with legacy TL072/TL082 layouts.
Technical Context
The TL062ID employs a JFET-input differential pair followed by a high-gain CMOS-compatible output stage, achieving >1012 Ω input resistance and latch-up-free operation. Its internal frequency compensation ensures stable unity-gain operation without external components across –40°C to 85°C ambient temperature.
Designed as a low-power counterpart to the TL072 and TL082 families, the TL062ID maintains comparable AC performance (1 MHz GBW, 3.5 V/µs slew rate) while reducing supply current by ~50%. It supports dual-supply operation from ±5 V to ±15 V and features output short-circuit protection with no need for external current-limiting resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA per amplifier - enables multi-channel battery-powered systems with weeks of runtime on coin cells. |
| Input Bias Current | ≤200 pA at 25°C - preserves signal integrity in high-impedance sensor interfaces (e.g., piezoelectric, pH electrodes). |
| Slew Rate | 3.5 V/µs typical - supports clean amplification of audio-band signals up to ~100 kHz at unity gain. |
| Unity-Gain Bandwidth | 1 MHz - sufficient for precision DC-coupled gain stages and active filters with cutoffs <100 kHz. |
| Common-Mode Range | –12 V to +15 V (with ±15 V supplies) - includes VCC+, allowing direct sensing of signals referenced to positive rail. |
| Input Offset Voltage | ≤15 mV - suitable for medium-accuracy applications like industrial transducer signal conditioning without trimming. |
| ESD Rating | 1.5 kV HBM - provides robustness against handling damage in automated assembly environments. |
Pinout & Package
TL062ID is supplied in an 8-pin SOIC (Small Outline Integrated Circuit) package measuring 4.90 mm × 6.00 mm, optimized for surface-mount reflow assembly and PCB space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads ≥10 kΩ; short-circuit protected to either supply rail. |
| 2 | IN– A | Inverting input of Amplifier A - high-impedance JFET node; sensitive to stray capacitance and leakage paths. |
| 3 | IN+ A | Non-inverting input of Amplifier A - same high-Z characteristics; common-mode range extends to VCC+. |
| 4 | VCC– | Negative supply rail - must be connected; not internally tied to substrate or ground. |
| 5 | IN+ B | Non-inverting input of Amplifier B - electrically isolated from Amplifier A; crosstalk attenuation ≥120 dB. |
| 6 | IN– B | Inverting input of Amplifier B - independent high-Z node; shares no internal nodes with Amplifier A inputs. |
| 7 | OUT B | Amplifier B output - fully independent output stage; supports separate feedback networks. |
| 8 | VCC+ | Positive supply rail - powers both amplifiers; requires local 0.1 µF ceramic decoupling adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Very low power consumption | 200 µA per amplifier enables dual op-amp operation from microamp-level power budgets. |
| JFET-input stage | Input impedance >1012 Ω minimizes loading on high-Z sources such as photodiode transimpedance nodes. |
| Output short-circuit protection | Allows safe operation into accidental shorts without external current limiting or thermal shutdown. |
| Internal frequency compensation | Guarantees stability in unity-gain follower and inverting configurations without external compensation. |
| Latch-up free operation | Prevents destructive parasitic thyristor conduction during overvoltage or ESD events. |

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 0.2 mA), faster slew rate (13 V/µs), lower input noise (18 nV/√Hz) | Better suited for wideband audio or high-speed data acquisition where power is not constrained | Choose TL072CDR when bandwidth and noise performance outweigh power budget limitations. |
| TL082CDR | Higher supply current (1.4 mA), higher input bias current (30 pA min vs 30 pA typ), no guaranteed latch-up immunity | Lower-cost option for general-purpose amplification where ESD robustness is secondary | Choose TL082CDR only in non-critical commercial applications with controlled ESD environments. |
Compared with TL072CDR and TL082CDR, the TL062ID offers the lowest quiescent power among TI's legacy JFET dual op-amps - critical for always-on sensor nodes - while trading off speed and noise for battery longevity and ruggedness in harsh industrial settings.

FAQ
What is the maximum supply voltage for TL062ID?
The TL062ID supports dual-supply operation with absolute maximum ratings of ±18 V. However, its recommended operating range is ±5 V to ±15 V. Operating beyond ±15 V risks exceeding thermal limits and degrading long-term reliability, even if within absolute max ratings. Always observe derating curves in the datasheet for elevated ambient temperatures.
Does TL062ID require external offset nulling components?
No, the TL062ID does not provide offset null pins and is not designed for external trimming. Its input offset voltage is specified at ≤15 mV (max) over temperature, and internal design eliminates dedicated nulling terminals. For applications requiring tighter offset control, consider the TL062AC variant or post-amplifier digital calibration.
Can TL062ID drive capacitive loads directly?
The TL062ID is not optimized for heavy capacitive loads. Driving >100 pF directly may cause instability or ringing due to phase margin reduction. For loads exceeding this, add a small series resistor (e.g., 10–100 Ω) between the output and capacitor, or use a unity-gain buffer stage with higher drive capability.
Is TL062ID pin-compatible with TL072 or TL082?
Yes, TL062ID uses the same SOIC-8 pinout as TL072CDR and TL082CDR, making it a drop-in replacement in existing layouts. However, due to its significantly lower supply current and reduced slew rate, verify loop stability and bandwidth requirements before substitution - especially in high-frequency or fast-settling applications.
What is the thermal resistance (RθJA) of TL062ID in SOIC-8 package?
The TL062ID in SOIC-8 (D package) has a junction-to-ambient thermal resistance (RθJA) of 97°C/W under standard JEDEC test conditions. This value assumes a 1-inch² copper pad with two vias; actual board layout significantly impacts real-world thermal performance. Derate power dissipation accordingly above 25°C ambient.
