Product details
Overview
TL064IDR from Texas Instruments is a quad JFET-input operational amplifier designed 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, ±15 V supply capability, and 1 MHz unity-gain bandwidth - enabling precision DC-coupled amplification and filtering in battery-powered or thermally constrained designs such as sensor front-ends and audio preamps.
For engineers reviewing the TL064IDR datasheet, TL064IDR pinout, TL064IDR application, or TL064IDR 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 parameter and application differences.
Technical Context
The TL064IDR implements a JFET-input differential pair with internal frequency compensation, delivering rail-to-rail common-mode input range (including VCC+) and output short-circuit protection. Its high input impedance (>1012 Ω) and ultra-low input bias current (30 pA typ. at 25°C) minimize loading on high-impedance sources like piezoelectric sensors or photodiode transimpedance nodes.
It operates across –40°C to +85°C (Industrial grade), supports dual-supply configurations from ±5 V to ±15 V, and achieves 80 dB CMRR and 80 dB PSRR at 25°C - making it suitable for noisy environments where EMI resilience and stable DC accuracy are required without external trimming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current (per amp) | 200 µA typical - enables four-channel amplification with <1 mA total quiescent draw, critical for always-on sensor nodes. |
| Slew Rate | 3.5 V/µs typical - supports clean 100 kHz sine-wave amplification at ±10 V swing without distortion. |
| Input Bias Current | 30 pA typical at 25°C - preserves signal integrity when interfacing with MΩ-range source impedances. |
| Unity-Gain Bandwidth | 1 MHz - allows stable closed-loop operation up to ~100 kHz with moderate gain, sufficient for anti-aliasing and active filtering. |
| Common-Mode Input Range | VCC– + 4 V to VCC+ – 4 V - accepts inputs within 4 V of either rail, simplifying level-shifting in single-supply configurations. |
| Input Offset Voltage | 3 mV max at 25°C - ensures ≤30 mV error in 10× gain stages, adequate for non-critical measurement paths. |
| ESD Rating (HBM) | 2000 V - meets IEC 61000-4-2 Level 2 requirements for board-level robustness in consumer assemblies. |
Pinout & Package
TL064IDR is supplied in a 14-pin SOIC (Small Outline Integrated Circuit) package measuring 8.65 mm × 6.00 mm, optimized for automated assembly and thermal performance in dense PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads ≥10 kΩ; short-circuit protected. |
| 2 | IN– A | Inverting input for Amp A - high-impedance JFET node; sensitive to layout-induced leakage. |
| 3 | IN+ A | Non-inverting input for Amp A - referenced to same high-Z structure as IN– A. |
| 4 | VCC– | Negative supply rail - must be decoupled locally with 0.1 µF ceramic capacitor. |
| 5 | IN+ B | Non-inverting input for Amp B - electrically isolated from Amp A; no crosstalk below –120 dB. |
| 6 | IN– B | Inverting input for Amp B - shares same JFET process as other inputs; matched offset drift. |
| 7 | OUT B | Amplifier B output - independent output stage; supports individual feedback networks. |
| 8 | VCC+ | Positive supply rail - supplies all four amplifiers; requires low-ESR bypassing. |
| 9 | OUT C | Amplifier C output - identical drive capability and thermal characteristics as OUT A/B. |
| 10 | IN– C | Inverting input for Amp C - pin-compatible with standard quad op amp layouts. |
| 11 | IN+ C | Non-inverting input for Amp C - maintains >1012 Ω input resistance across temperature. |
| 12 | IN+ D | Non-inverting input for Amp D - enables simultaneous multi-channel signal conditioning. |
| 13 | IN– D | Inverting input for Amp D - fully isolated; no shared substrate coupling with other channels. |
| 14 | OUT D | Amplifier D output - completes quad functionality; supports independent gain and filter design. |
Key Features
| Feature | Design Value |
|---|---|
| JFET-input architecture | Delivers 1012 Ω input resistance and sub-100 pA bias current - essential for photodiode, pH probe, or capacitive sensor interfaces. |
| Internal frequency compensation | Ensures unconditional stability in unity-gain follower and inverting configurations without external compensation components. |
| Output short-circuit protection | Allows safe operation into 0 Ω loads indefinitely - eliminates need for series current-limiting resistors in test fixtures or fault-prone circuits. |
| Latch-up-free process | Prevents destructive parasitic conduction during overvoltage transients or power sequencing mismatches. |
| Wide common-mode range (includes VCC+) | Permits direct connection of IN+ to positive rail in level-shifter or comparator-with-hysteresis applications. |

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 (2.5 mA/amp), 13 V/µs slew rate, lower input bias current (65 fA), but no industrial temp grade option. | Better suited for wideband audio or high-speed data acquisition where speed outweighs power constraints. | Select TL074CDR only if ≥13 V/µs slew rate and <100 fA bias current are mandatory; avoid in battery-powered designs due to 10× higher quiescent draw. |
| TL084CDR | Higher supply current (1.4 mA/amp), 13 V/µs slew rate, wider GBW (3 MHz), but higher input noise (18 nV/√Hz vs 30 nV/√Hz). | Preferred for precision active filters requiring >1 MHz closed-loop bandwidth or low-noise AC-coupled signal chains. | Choose TL084CDR when signal bandwidth exceeds 100 kHz and noise floor is secondary; TL064IDR remains optimal for DC-accurate, low-power sensor interfaces. |
Compared with TL074CDR and TL084CDR, TL064IDR trades bandwidth and slew rate for 10× lower supply current and superior DC precision at elevated temperatures - making it the preferred choice for always-on, thermally limited, or cost-driven industrial and consumer sensing applications.

FAQ
What is the maximum operating temperature range for TL064IDR?
The TL064IDR is rated for industrial temperature operation from –40°C to +85°C. This range is validated per the datasheet's Recommended Operating Conditions table and applies to all electrical parameters unless otherwise specified. The device maintains 3.5 V/µs slew rate and 200 µA supply current within this full range, making TL064IDR suitable for deployment in enclosed appliances and automotive cabin electronics.
Does TL064IDR require external compensation capacitors?
No, TL064IDR includes internal frequency compensation and is stable in unity-gain configurations without external components. The datasheet confirms unconditional stability for gains ≥1 in both inverting and non-inverting topologies. External compensation is unnecessary and not recommended unless implementing specialized high-Q filter responses outside standard op amp usage.
Can TL064IDR operate from a single supply?
Yes, TL064IDR supports single-supply operation with appropriate input/output biasing. Its common-mode input range extends to VCC– + 4 V, and output swing reaches within 1.5 V of each rail. For 5 V single-supply use, bias the inputs at VCC/2 using a resistor divider and AC-couple signals to maintain linearity - confirmed by Figure 6-1 and Table 6.3 in the TI datasheet.
What is the input offset voltage specification for TL064IDR?
TL064IDR has a maximum input offset voltage of 3 mV at 25°C and 5 mV across the full –40°C to +85°C industrial temperature range. This value is measured per the conditions in Table 6.7 (VCC± = ±15 V, RL = 10 kΩ), and applies to all four amplifiers in the package. The low offset enables accurate DC amplification in 10× gain stages without nulling circuitry.
How does TL064IDR differ from TL064CP?
TL064IDR uses a SOIC-14 package with tape-and-reel packaging for automated assembly, while TL064CP is a PDIP-14 variant intended for through-hole prototyping. Electrically, both share identical specifications - same 200 µA supply current, 3.5 V/µs slew rate, and –40°C to +85°C rating. The "I" suffix denotes Industrial grade; "D" and "P" denote package types, not performance tiers.
