Product details
Overview
TL034ACD from Texas Instruments is a quad FET-input operational amplifier optimized for low-power, low-offset precision analog signal conditioning in industrial and energy systems. It delivers 1.1 MHz unity-gain bandwidth, ±15 V or ±5 V dual-supply operation, 120 μA typical supply current per amplifier, and 0.7 mV max input offset voltage (25°C) with 11.6 μV/°C tempco - enabling high-impedance sensor interfacing in solar inverters and motor drive feedback loops.
For engineers reviewing the TL034ACD datasheet, TL034ACD pinout, TL034ACD application, or TL034ACD equivalent, this page provides verified specifications, validated SOIC-14 package details, real-world use cases in AC drive control and UPS monitoring, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The TL034ACD uses TI's enhanced LinCMOS FET process to achieve higher slew rate (2.9 V/μs positive, 5.1 V/μs negative) and improved DC performance over legacy TL06x amplifiers - without increasing quiescent current. Its 10¹² Ω input resistance and 4 pF input capacitance support stable operation with high-Z sources like piezoelectric sensors or photodiode transimpedance stages.
Designed for dual-supply operation, it requires attention to common-mode input range (–11.5 V to +14 V at ±15 V supplies) and output swing limits (±14.955 V into 10 kΩ). Single-supply use mandates external DC biasing and virtual-ground generation via devices like the TLE2426.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±5 V to ±15 V - supports standard industrial rail configurations and enables direct replacement of TL064 in existing designs. |
| Input Offset Voltage | 0.7 mV max (25°C), 3.7 mV max (0°C to 70°C) - enables accurate DC-coupled signal amplification in precision current sensing. |
| Unity-Gain Bandwidth | 1.1 MHz - sufficient for closed-loop control of PWM-driven motor phases up to ~100 kHz switching frequency. |
| Slew Rate | 2.9 V/μs (positive), 5.1 V/μs (negative) - ensures faithful reproduction of fast transient signals in UPS line-synchronization circuits. |
| Input Resistance | 10¹² Ω - minimizes loading error when buffering high-impedance pH electrodes or thermocouple cold-junction compensation networks. |
| Common-Mode Rejection | 94 dB min - suppresses noise coupling from shared ground paths in multi-channel inverter gate driver monitoring. |
| Supply Current per Amp | 120–280 μA - allows four independent channels in battery-backed metering systems with <1.2 mW total quiescent power at ±5 V. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad FET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CD | Higher 3 mV max VIO (25°C), 13 V/μs slew rate, 3 mA supply current - trades precision for speed and drive strength. | Preferred in audio preamps and wideband active filters where offset is less critical than bandwidth. | Select TL074CD only if system requires >3 MHz GBW and can tolerate 4× higher quiescent power. |
| TLV2464IDR | Rail-to-rail output, 0.6 mV max VIO, 0.65 mA supply current - optimized for single-supply 2.7–6 V operation with virtual-ground dependency removed. | Used in portable instrumentation and battery-powered data loggers where supply headroom is constrained. | Choose TLV2464IDR when operating from 3.3 V or lower rails and RRO output swing is mandatory for full-scale ADC utilization. |
Compared with TL034ACD, TL074CD offers faster response but sacrifices DC precision and power efficiency, while TLV2464IDR enables true single-supply operation at the cost of reduced output voltage swing headroom at ±15 V rails.

FAQ
What is the maximum operating temperature range for TL034ACD?
The TL034ACD is characterized for operation from 0°C to 70°C (C-suffix grade). Its electrical specifications - including 0.7 mV max input offset voltage and 120 μA typical supply current - are guaranteed across this full commercial temperature range, making it suitable for indoor industrial enclosures and climate-controlled UPS systems.
Does TL034ACD support single-supply operation?
TL034ACD is designed for dual-supply operation and does not support true single-supply use without external biasing. When operated from a single rail, DC biasing of both inputs to mid-supply and termination of loads to a virtual ground (e.g., using TI's TLE2426) is required to stay within common-mode and output swing limits - unlike rail-to-rail amplifiers such as TLV2464IDR.
How does TL034ACD differ from TL034CD in precision performance?
TL034ACD features on-chip offset-voltage trimming, resulting in tighter DC specs: 0.7 mV max VIO at 25°C versus 0.79 mV for TL034CD, and 3.7 mV max over 0°C–70°C versus 6.2 mV. This trimming reduces calibration burden in production test and improves long-term stability, especially in temperature-varying environments like outdoor solar installations.
Can TL034ACD replace TL064 in existing designs?
Yes - TL034ACD is a direct upgrade for TL064, sharing identical SOIC-14 pinout, supply voltage range (±5 V to ±15 V), and footprint. It improves upon TL064 with 2× higher slew rate (2.9 V/μs vs 1.5 V/μs), lower input offset (0.7 mV vs 3 mV), and better CMRR (94 dB vs 80 dB), enabling drop-in replacement in most legacy designs without layout changes.
What is the typical input bias current of TL034ACD at 70°C?
At 70°C, TL034ACD exhibits a typical input bias current of 80 pA, with a maximum of 400 pA. This ultra-low bias current - enabled by its FET-input architecture - ensures minimal voltage error across high-value feedback resistors (e.g., 1 MΩ), preserving gain accuracy in precision integrator and filter circuits used in motor control loop compensation.
