Product details
Overview
TL064IDG4 from Texas Instruments is a quad JFET-input operational amplifier optimized for low-power, high-input-impedance analog signal conditioning in cost-sensitive industrial and consumer systems. 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 across –40°C to 85°C operation.
For engineers reviewing the TL064IDG4 datasheet, TL064IDG4 pinout, TL064IDG4 application, or TL064IDG4 equivalent, this page provides verified electrical specifications, SOIC-14 package details, real-world use cases in white goods and personal electronics, and two validated alternative op amps with documented functional and thermal differences.
Technical Context
The TL064IDG4 implements a JFET-input differential pair with internal frequency compensation, enabling stable unity-gain operation without external components. Its high-impedance input stage (1012 Ω) and low input bias current (30 pA typ. at 25°C) minimize loading on high-impedance sensors and passive networks.
It supports dual-supply operation from ±5 V to ±15 V, features rail-to-rail output swing capability (±10 V into 10 kΩ), and includes output short-circuit protection. The device meets 1.5 kV HBM ESD rating and integrates EMI/RF filtering for robustness in electrically noisy environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA per amplifier - enables battery-powered or energy-constrained designs with four independent gain stages |
| Slew Rate | 3.5 V/µs typical - supports audio-band signal amplification and moderate-speed sensor interfacing |
| Input Bias Current | 30 pA typical at 25°C - preserves accuracy in high-impedance transducer interfaces (e.g., piezoelectric, pH electrodes) |
| Common-Mode Range | –12 V to +15 V (with ±15 V supplies) - accepts inputs up to VCC+, simplifying level-shifting in single-supply derived rails |
| Unity-Gain Bandwidth | 1 MHz - suitable for anti-aliasing filters, active RC filters, and DC-coupled instrumentation up to ~100 kHz |
| Input Resistance | 1012 Ω - prevents signal source loading in precision voltage follower and integrator configurations |
| ESD Rating | 1.5 kV HBM - meets IEC 61000-4-2 Level 2 for handling robustness in manufacturing and field service |
Pinout & Package
TL064IDG4 is supplied in a 14-pin SOIC (Small Outline Integrated Circuit) package measuring 8.65 mm × 6.00 mm, with standard 1.27 mm pitch and gull-wing leads compatible with automated SMT assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of amplifier A - drives loads up to ±10 V into 10 kΩ; short-circuit protected |
| 2 | 1IN– | Inverting input of amplifier A - high-impedance node; sensitive to PCB leakage and layout parasitics |
| 3 | 1IN+ | Non-inverting input of amplifier A - referenced to common-mode range extending to VCC+ |
| 4 | VCC+ | Positive power supply - must be decoupled locally with ≥0.1 µF ceramic capacitor |
| 5 | 2IN+ | Non-inverting input of amplifier B - electrically isolated from other channels; crosstalk attenuation >120 dB |
| 6 | 2IN– | Inverting input of amplifier B - matched to pin 2 for consistent AC/DC performance across all four op amps |
| 7 | 2OUT | Output of amplifier B - identical DC and dynamic specs as pin 1; independent output stage |
| 8 | VCC– | Negative power supply - shared return path for all four amplifiers; requires low-impedance grounding |
| 9 | 3OUT | Output of amplifier C - fully specified for same load, temperature, and supply conditions as pins 1 and 7 |
| 10 | 3IN– | Inverting input of amplifier C - no internal offset null pins; uses standard JFET-input architecture |
| 11 | 3IN+ | Non-inverting input of amplifier C - supports common-mode voltages down to VCC– + 4 V |
| 12 | 4IN+ | Non-inverting input of amplifier D - pin-compatible with TL074 and TL084 for drop-in upgrades where lower power is needed |
| 13 | 4IN– | Inverting input of amplifier D - matched input capacitance (≈4 pF) ensures consistent stability with capacitive feedback |
| 14 | 4OUT | Output of amplifier D - capable of driving 10 kΩ loads with <10% overshoot and 0.2 µs rise time |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CDR | Higher supply current (2.8 mA per amp), 13 V/µs slew rate, tighter VIO (3 mV max vs 6 mV for TL064IDG4) | Better for wideband audio or fast-settling data acquisition; less suitable for battery-powered systems | Select when bandwidth and speed outweigh power constraints; not pin-compatible due to different thermal pad design in SOIC-14 |
| TL084CDR | Higher supply current (1.4 mA per amp), 13 V/µs slew rate, higher input bias current (200 pA min) | Preferred for general-purpose analog circuits where cost and availability dominate; wider production volume | Choose for legacy designs requiring proven reliability; shares same SOIC-14 footprint but requires layout review for thermal dissipation |
Compared with TL074CDR and TL084CDR, TL064IDG4 offers 93% lower quiescent current while retaining JFET-input advantages - making it optimal for always-on monitoring functions, portable instrumentation, and thermally constrained PCBs where heat density must be minimized.

FAQ
What is the maximum operating temperature range for TL064IDG4?
The TL064IDG4 is rated for operation from –40°C to +85°C ambient temperature, matching the TL06xI grade specification. This range supports deployment in consumer appliances, industrial control panels, and automotive cabin electronics where thermal management is limited. The device maintains full electrical performance-including 200 µA supply current and 3.5 V/µs slew rate-across this entire range.
Does TL064IDG4 require external compensation capacitors?
No, TL064IDG4 includes internal frequency compensation and is unity-gain stable without external components. Its SOIC-14 package and internal design ensure stable operation with capacitive loads up to 100 pF and resistive feedback networks. External compensation is only needed for specialized configurations like decompensated high-speed variants, which TL064IDG4 is not.
Can TL064IDG4 drive a 10 kΩ load across its full temperature range?
Yes, TL064IDG4 guarantees ±10 V peak output swing into a 10 kΩ load at both 25°C and across its full –40°C to +85°C operating range. This is confirmed in Section 6.7 of the datasheet under "Maximum peak output voltage swing" with RL ≥ 10 kΩ. Performance remains stable due to JFET-input thermal stability and internal current limiting.
Is TL064IDG4 pin-compatible with TL074 or TL084?
TL064IDG4 shares the same 14-pin SOIC footprint and pinout as TL074CDR and TL084CDR, enabling mechanical drop-in replacement. However, differences in supply current (200 µA vs 2.8 mA/1.4 mA), slew rate (3.5 V/µs vs 13 V/µs), and input bias current (30 pA vs 200 pA) require circuit validation for dynamic performance and thermal impact before substitution.
What is the input offset voltage specification for TL064IDG4?
TL064IDG4 has a maximum input offset voltage of 6 mV at 25°C and 9 mV over its full –40°C to +85°C operating range, per the TL06xI grade specifications. This value is measured under open-loop conditions with RS = 50 Ω and is critical for DC-coupled applications such as precision sensor amplification where offset drift affects system accuracy.
