Product details
Overview
TL034IDRG4 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 supply operation, 120 μA per amplifier supply current, 0.7–0.91 mV typical input offset voltage (I-suffix), and 1012 Ω input resistance - enabling high-impedance sensor interfacing in solar inverters and motor drive feedback loops.
For engineers reviewing the TL034IDRG4 datasheet, TL034IDRG4 pinout, TL034IDRG4 application, or TL034IDRG4 equivalent, this page provides verified electrical specifications, SOIC-14 package details, real-world use cases in AC/DC power conversion and servo control, and two validated alternative op-amps with documented performance trade-offs.
Technical Context
The TL034IDRG4 belongs to the TL03x family of enhanced-FET op-amps, offering improved DC accuracy and AC performance over legacy TL06x devices without increased power consumption. Its JFET input stage enables ultra-low input bias current (≤200 pA at 25°C) and high common-mode rejection (≥75 dB), critical for precision transducer amplification.
Designed for dual-supply operation (±5 V to ±15 V), it requires careful attention to common-mode input voltage limits (e.g., −11.5 V to +14 V at ±15 V supplies) and output swing constraints. Single-supply use demands external DC biasing and virtual-ground generation via components like the TLE2426.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±5 V to ±15 V - supports standard industrial dual-rail power domains without level-shifting. |
| Input Offset Voltage (Typ) | 0.7 mV (TL034AI, 25°C) - enables sub-mV error budgets in 12-bit+ data acquisition front-ends. |
| Unity-Gain Bandwidth | 1.1 MHz - sufficient for anti-aliasing filters and closed-loop control up to ~100 kHz. |
| Slew Rate (Typ) | 2.0 V/μs (positive), 3.9 V/μs (negative) - handles fast transient signals in motor current sensing. |
| Input Bias Current (Max) | 200 pA at 25°C - preserves signal integrity when amplifying outputs from piezoelectric or pH sensors. |
| Common-Mode Rejection Ratio | 75 dB min (±15 V) - rejects noise coupling from shared ground paths in multi-channel power-stage monitoring. |
| Supply Current per Amplifier | 120–250 μA - allows four independent channels in battery-powered or thermally constrained designs. |
Pinout & Package
TL034IDRG4 is supplied in a 14-pin SOIC (D) package measuring 8.65 mm × 6.00 mm, with standard JEDEC MS-012AC footprint and gull-wing leads. Thermal resistance θJA is 80 °C/W, supporting operation up to 85°C ambient with moderate PCB copper area.

| VCC− | Power supply negative | Connects to −V rail; must be routed with low-inductance path to minimize PSRR degradation. |
| 4IN+ | Non-Inverting Input, channel 4 | Fourth independent input; suitable for auxiliary functions like temperature compensation. |
| 4IN− | Inverting Input, channel 4 | Completes full quad configuration; supports 4-channel instrumentation or filter banks. |

Key Features
| Feature | Design Value |
|---|---|
| FET input architecture | 1012 Ω input resistance and ≤200 pA bias current enable direct connection to high-Z sources (e.g., photodiodes, strain gauges). |
| On-chip offset trimming (I-suffix) | Reduces initial VIO to 0.7 mV typical, lowering calibration overhead in factory-trimmed systems. |
| Low quiescent current | 120 μA per amplifier allows four-channel operation at <500 μA total - ideal for always-on monitoring circuits. |
| Enhanced slew rate vs. TL064 | 3.9 V/μs negative slew rate improves settling time in pulse-width modulated (PWM) feedback loops. |
| Wide supply range compatibility | Operates from ±5 V to ±15 V without derating - simplifies design reuse across 12 V and 24 V industrial platforms. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad FET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CDR | Higher slew rate (13 V/μs), higher supply current (1.4 mA/amplifier), no on-chip offset trim. | Better for wideband active filters; unsuitable for ultra-low-power standby modes. | Select when bandwidth >3 MHz is required and power budget allows >5 mA total. |
| OPA4134UA | Lower VIO (0.5 mV typ), lower noise (8 nV/√Hz), higher cost, SOIC-14 pinout compatible. | Preferred for audio and precision metrology; overqualified for industrial motor control. | Choose when sub-0.5 mV offset and <10 nV/√Hz noise are mandatory, and BOM cost is secondary. |
Compared with TL034IDRG4, TL074CDR trades 10× higher power for 6× faster response, while OPA4134UA delivers superior DC precision and noise at 3× cost - making TL034IDRG4 the optimal balance of micropower operation, adequate speed, and industrial temperature range for cost-sensitive embedded power electronics.

FAQ
What is the operating temperature range for TL034IDRG4?
The TL034IDRG4 is characterized for operation from −40°C to +85°C, matching the I-suffix industrial grade specification. This range is validated across all key parameters including input offset voltage, supply current, and common-mode rejection ratio - ensuring reliable performance in outdoor solar installations and factory-floor motor drives.
Can TL034IDRG4 operate from a single supply?
Yes, TL034IDRG4 can operate from a single supply, but requires external DC biasing of input signals and termination of loads to a virtual ground (e.g., using TI's TLE2426). The device's common-mode input range does not extend to the negative rail, so mid-supply referencing is essential to avoid clipping or phase reversal.
What is the maximum output current capability of TL034IDRG4?
TL034IDRG4 supports ±40 mA output current per amplifier, as defined in Absolute Maximum Ratings. However, sustained operation above ±20 mA may cause thermal drift or reduced open-loop gain; for continuous 30 mA loads, derating or heatsinking is recommended.
How does TL034IDRG4 compare to TL064 in terms of power and performance?
TL034IDRG4 consumes comparable supply current (120 μA vs. 200 μA for TL064) while delivering 2× higher slew rate (3.9 V/μs vs. 3.5 V/μs) and 30% lower input offset voltage (0.7 mV vs. 1.0 mV typical). It also features on-chip offset trimming - a key upgrade for production calibration efficiency.
Is TL034IDRG4 pin-compatible with other quad op-amps in SOIC-14 packages?
TL034IDRG4 uses the industry-standard SOIC-14 pinout defined in Table 4-4 of its datasheet, matching TL074, TL084, and OPA4134. However, differences in input stage (JFET vs. bipolar), supply current, and ESD protection require verification of biasing and stability in drop-in replacements.
