Product details
Overview
TLE2074ACDW from Texas Instruments is a quad-channel, low-noise, high-speed JFET-input operational amplifier in SOIC-14 package, featuring ±3 mV max input offset voltage (25°C), 10 MHz unity-gain bandwidth, 32 V/μs slew rate, and operation across ±2.25 V to ±19 V supply rails. It delivers 17 nV/√Hz input voltage noise at 1 kHz and supports rail-to-rail differential input voltage, making it suitable for precision analog front-ends in digital multimeters and oscilloscope signal conditioning stages.
For engineers reviewing the TLE2074ACDW datasheet, TLE2074ACDW pinout, TLE2074ACDW application, or TLE2074ACDW equivalent, key selection criteria include its 14-pin SOIC (DW) package thermal performance (θJA = 57.3°C/W), guaranteed AC performance at ±15 V supplies, low 15 pA typical input bias current, and compatibility with high-dynamic-range data acquisition systems requiring stable DC precision and wide bandwidth.
Technical Context
The TLE2074ACDW implements a JFET-input stage with on-chip Zener trimming for offset voltage control, enabling low drift and high input impedance (>100 MΩ common-mode, >6 TΩ differential). Its internal compensation ensures unity-gain stability while supporting fast settling (0.4 μs to 1 mV for 10 V step) and low distortion (0.0032% THD+N at 1 kHz).
Designed for dual-supply operation, it accepts common-mode inputs beyond rails (−0.9 V to +5 V at ±5 V, −10.9 V to +15 V at ±15 V), withstands differential inputs up to supply rails, and maintains CMRR ≥85 dB and PSRR ≥82 dB across its 0°C to 70°C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-channel signal conditioning without board-level duplication. |
| Supply Voltage Range | ±2.25 V to ±19 V - supports wide dynamic signal range in industrial and test equipment power domains. |
| Unity-Gain Bandwidth | 10.6 MHz - allows stable closed-loop operation up to 10 MHz with gain ≥1, critical for high-fidelity waveform reproduction. |
| Slew Rate | 32 V/μs - ensures faithful amplification of fast transients (e.g., pulse edges in DMM sampling circuits). |
| Input Offset Voltage (max) | 3 mV at 25°C - defines worst-case DC error in precision gain stages; trimmed for C-suffix commercial temperature range. |
| Input Voltage Noise | 17 nV/√Hz at 1 kHz - sets fundamental noise floor for low-level sensor signal amplification in metering applications. |
| Input Bias Current (typ) | 15 pA - minimizes voltage drop across high-impedance source networks (e.g., piezoelectric sensors, photodiode TIA feedback). |
Pinout & Package
Package: SOIC-14 (DW), 10.3 mm × 10.3 mm, surface-mount, tape-and-reel compatible (R suffix option available).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 10, 14 | Output | Amplified output per channel; capable of ±14.5 V swing into 20 mA load at ±15 V supplies. |
| 2, 6, 9, 13 | Inverting Input (–) | Differential input node; accepts signals up to supply rails; high impedance (>100 MΩ) preserves source integrity. |
| 3, 7, 8, 12 | Non-inverting Input (+) | Differential input node; same rail-to-rail common-mode range and impedance as inverting input. |
| 4 | VCC– | Negative supply rail connection; must be decoupled locally to minimize noise coupling into all four channels. |
| 11 | VCC+ | Positive supply rail connection; shared power path for quad amplifier; requires low-ESR bulk + ceramic decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Low input voltage noise | 17 nV/√Hz at 1 kHz - directly reduces integrated noise in bandwidth-limited measurement paths (e.g., 10 Hz–100 kHz DMM AC ranges). |
| Rail-to-rail differential input | Supports inputs up to ±19 V differential - eliminates external level-shifting in high-voltage sensor interfaces (e.g., motor phase current sensing). |
| Unity-gain stable | No external compensation required - simplifies layout and reduces BOM count in gain-of-1 buffer and active filter designs. |
| High CMRR & PSRR | ≥85 dB CMRR, ≥82 dB PSRR - rejects power supply ripple and common-mode interference in noisy industrial environments. |
| Low input bias current | 15 pA typical - prevents significant offset errors when driving from megaohm-level sources (e.g., pH electrodes, thermocouple cold-junction compensation). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CDR | Higher 30 nV/√Hz noise, 3 mV VIO max, same SOIC-14 package but lower 3 MHz GBW and 13 V/μs slew rate. | Acceptable in cost-sensitive, lower-bandwidth metering where noise <25 nV/√Hz is tolerable. | Choose TL074CDR only if bandwidth ≤3 MHz and noise budget permits 76% higher input noise than TLE2074ACDW. |
| OPA4134UA | Lower 8 nV/√Hz noise, 1 mV VIO max, 8 MHz GBW, ±18 V supply, SOIC-14, but higher 4 mA/ch supply current vs. 2.48 mA/ch. | Better for ultra-low-noise audio or precision instrumentation where power efficiency is secondary. | Select OPA4134UA when 8 nV/√Hz noise and 1 mV VIO outweigh the 64% higher quiescent power versus TLE2074ACDW. |
Compared with TL074CDR, TLE2074ACDW provides 43% lower noise and >2× bandwidth; compared with OPA4134UA, it trades 53% less noise for 33% higher bandwidth and 42% lower supply current-making it optimal for battery-powered or thermally constrained DMM and oscilloscope front-ends.

FAQ
What is the maximum supply voltage rating for the TLE2074ACDW?
The TLE2074ACDW has an absolute maximum supply voltage rating of ±19 V, with recommended operation from ±2.25 V to ±19 V. This wide rail capability allows direct use in high-dynamic-range applications such as oscilloscope vertical amplifiers and EV charging station DC-link monitors without external level-shifting circuitry. Exceeding ±19 V risks permanent damage per TI's Absolute Maximum Ratings table.
Does the TLE2074ACDW support rail-to-rail input operation?
The TLE2074ACDW supports rail-to-rail *differential* input voltage (up to ±19 V), and its common-mode input voltage range extends to (VCC– – 0.9 V) and (VCC+ + 0.5 V) at ±5 V supplies, or (VCC– – 10.9 V) and (VCC+ + 0.5 V) at ±15 V supplies. It does not support true rail-to-rail *common-mode* input swing to both supply rails simultaneously, but exceeds rail limits on the negative side-critical for single-supply-compatible configurations with proper biasing.
What is the thermal resistance (θJA) of the TLE2074ACDW in its SOIC-14 (DW) package?
The TLE2074ACDW in the DW package has a junction-to-ambient thermal resistance (θJA) of 57.3°C/W under standard JEDEC PCB mounting conditions (2s2p copper). This value is confirmed in Section 6.1 of the TI datasheet and reflects its superior thermal performance relative to PDIP or smaller SOIC variants-enabling higher continuous output current in compact layouts without forced airflow.
Is the TLE2074ACDW unity-gain stable?
Yes, the TLE2074ACDW is internally compensated for unity-gain stability, as verified by its 56°–57° phase margin at unity gain (Section 6.4/6.6/6.10) and explicit "unity-gain stable" designation in the Features section. This eliminates the need for external compensation capacitors in gain-of-1 buffers, active filters, or transimpedance amplifier configurations-reducing design risk and board area.
How does the input offset voltage specification of the TLE2074ACDW compare to the standard TLE2074CDW variant?
The TLE2074ACDW specifies a maximum input offset voltage of 3 mV at 25°C, whereas the non-A variant TLE2074CDW is rated at 5 mV max under identical conditions (Table 4-3). This tighter 40% offset spec makes the 'A' grade preferred for precision applications like 4½-digit DMMs and metrology-grade electricity meters where initial DC error directly impacts system accuracy class compliance.
