Product details
Overview
TL062BCDG4 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, and ±11 V common-mode input range extending to VCC+, enabling use in rail-to-rail-sensing front-ends for industrial sensor interfaces.
For engineers reviewing the TL062BCDG4 datasheet, TL062BCDG4 pinout, TL062BCDG4 application, or TL062BCDG4 equivalent, key selection criteria include its JFET-input bias current (≤200 pA at 25°C), unity-gain bandwidth (1 MHz), input offset voltage (max 3 mV), and SOIC-8 package compatibility with legacy TL072/TL082 layouts.
Technical Context
The TL062BCDG4 implements a two-stage JFET-input op amp architecture with internal frequency compensation, delivering stable unity-gain operation without external compensation. Its high-impedance differential pair enables ultra-low input bias current while maintaining 80 dB CMRR and 80 dB PSRR across 0°C to 70°C.
Designed as a lower-power counterpart to the TL072 and TL082 families, it retains identical pinout and AC performance (1 MHz GBW, 3.5 V/µs slew) but reduces quiescent current by ~50%, making it suitable for battery-powered instrumentation and always-on sensor signal chains where thermal dissipation and standby power are constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA per amplifier - enables dual-channel operation from microamp-level supplies; supports >1-year battery life in 3.3 V coin-cell sensor nodes. |
| Input Bias Current | ≤200 pA at 25°C - preserves signal integrity in high-impedance pH, photodiode, or piezoelectric sensor interfaces without loading. |
| Common-Mode Range | –12 V to +15 V (with ±15 V supplies) - includes VCC+, allowing direct sensing of signals referenced to positive rail. |
| Slew Rate | 3.5 V/µs - supports clean amplification of audio-band and medium-speed control signals (e.g., 10 kHz sine at 10 Vpp). |
| Unity-Gain Bandwidth | 1 MHz - sufficient for anti-aliasing filters, active RC stages, and closed-loop gain ≥10 up to ~100 kHz. |
| Input Offset Voltage | Max 3 mV at 25°C - ensures ≤0.3% gain error in 1 V full-scale measurement paths without trimming. |
| ESD Rating | 1.5 kV HBM - meets IEC 61000-4-2 Level 2 for robustness in unshielded industrial environments. |
Pinout & Package
TL062BCDG4 is housed in an 8-pin SOIC (D) package measuring 4.90 mm × 6.00 mm, with standard JEDEC MS-012AC footprint and 1.27 mm pitch. The package supports reflow soldering per IPC/JEDEC J-STD-020 and operates up to 125°C junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads ≥10 kΩ; short-circuit protected to ground or either supply rail. |
| 2 | IN− A | Inverting input A - high-impedance JFET node; connects to feedback network in inverting configurations. |
| 3 | IN+ A | Non-inverting input A - accepts DC- or AC-coupled signals within common-mode range; no internal offset null pins. |
| 4 | VCC− | Negative supply - must be ≤ –5 V for specified operation; decoupling capacitor required near pin. |
| 5 | IN+ B | Non-inverting input B - electrically isolated from Channel A; crosstalk attenuation ≥120 dB at 100× gain. |
| 6 | IN− B | Inverting input B - matches IN− A in bias current and offset characteristics; supports matched dual-channel designs. |
| 7 | OUT B | Amplifier B output - independent output stage; shares VCC+/VCC− rails with Channel A. |
| 8 | VCC+ | Positive supply - accepts 5 V to 15 V; internal EMI/RF filtering reduces susceptibility to switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| JFET-input stage | Input impedance ≥1 TΩ enables direct connection to megohm-range sensors without signal degradation. |
| Low power consumption | 6 mW total dissipation per amplifier allows dual-channel operation in thermally constrained enclosures. |
| Output short-circuit protection | Continuous safe shorting to either rail or ground eliminates need for external current-limiting resistors. |
| Wide common-mode range | Operates with inputs up to VCC+, simplifying single-supply level-shifting and high-side current sensing. |
| Internal frequency compensation | Guarantees stability in unity-gain follower and inverting configurations without external compensation components. |

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 (2.5 mA per amp), 13 V/µs slew rate, tighter offset (10 mV max) | Better for wideband audio or fast transient response; unsuitable for <100 µA power budgets | Select when speed outweighs power; verify thermal margin due to 4× higher dissipation |
| TL082CDR | Higher supply current (1.4 mA per amp), 13 V/µs slew, lower input capacitance (2.5 pF vs 4 pF) | Preferred for high-frequency active filters; less optimal for ultra-high-Z sensor nodes due to higher bias current (2 nA) | Choose for >100 kHz signal paths; avoid in photodiode or piezo applications requiring sub-nA bias |
Compared with TL072CDR and TL082CDR, TL062BCDG4 trades bandwidth and slew rate for 5× lower quiescent current and 10× lower input bias current-making it the only option among the three viable for multi-year battery-powered sensor nodes with megohm-level source impedances.

FAQ
What is the maximum operating temperature range for TL062BCDG4?
The TL062BCDG4 is rated for operation from 0°C to +70°C ambient temperature, consistent with its 'C' grade designation. Its SOIC-8 package supports junction temperatures up to 150°C, but sustained operation above 70°C requires derating supply current and verifying thermal design per RθJA = 97°C/W.
Does TL062BCDG4 require external compensation capacitors?
No, TL062BCDG4 features internal frequency compensation and is stable in unity-gain configurations without external components. This eliminates layout complexity and component count in voltage-follower, inverting, and non-inverting amplifier designs per the manufacturer's recommended test circuits.
Can TL062BCDG4 operate from a single 5-V supply?
Yes, TL062BCDG4 supports single-supply operation with VCC+ = 5 V and VCC− = 0 V. However, its common-mode input range extends only to VCC− + 4 V and VCC+ – 4 V, limiting usable input swing to 1 V–4 V; rail-to-rail input variants are not supported.
How does TL062BCDG4 compare to TL062CP in terms of performance?
TL062BCDG4 (SOIC-8) and TL062CP (PDIP-8) share identical electrical specifications-including 200 µA supply current, 3 mV max offset, and 3.5 V/µs slew-but differ in package thermal resistance (97°C/W vs 85°C/W) and moisture sensitivity (MSL 1 vs MSL 3). Layout and reflow requirements differ accordingly.
Is TL062BCDG4 pin-compatible with TL072 or TL082 op amps?
Yes, TL062BCDG4 uses the industry-standard dual op amp pinout (SOIC-8) and is fully pin-compatible with TL072 and TL082. This allows drop-in replacement in existing designs where lower power consumption and reduced input bias current are beneficial-without PCB or schematic changes.
