Product details
Overview
TL052MFKB from Texas Instruments is a dual-channel, JFET-input operational amplifier with on-chip offset-voltage trimming, 4.5 MHz unity-gain bandwidth, 17.8 V/μs slew rate (±15 V), and 0.65 mV max input offset voltage at 25°C. It operates from ±5 V to ±15 V supplies and delivers precision signal conditioning in audio preamplifiers, sensor interfaces, and instrumentation circuits.
For engineers reviewing the TL052MFKB datasheet, TL052MFKB pinout, TL052MFKB application, or TL052MFKB equivalent, this page provides verified pin functions, real-world application contexts, confirmed alternative parts with documented differences, and supply-chain support for industrial and test-equipment design cycles.
Technical Context
The TL052MFKB uses enhanced JFET-input process technology to achieve lower input offset voltage and improved DC stability versus TL072/TL082, while maintaining FET-level input impedance (>10¹² Ω) and bipolar-like output drive capability. Its internal architecture includes trimmed input-stage transistors and optimized compensation for stable unity-gain operation with ≤100 pF capacitive loads.
It supports dual-supply operation only, with common-mode input range of –11 V to +11 V (±15 V) and output swing of ±11.5 V into 2 kΩ. Input bias current remains below 0.2 nA at 85°C, enabling high-impedance source interfacing without significant DC error.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual FET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CDR | Higher input offset (3 mV max), higher 1/f noise (70 nV/√Hz at 10 Hz), no on-chip trimming. | Acceptable where cost is primary and DC accuracy < 1 mV not required. | Choose TL072CDR only if legacy design reuse or BOM consolidation outweighs need for improved DC performance. |
| OPA2134UA | Lower noise (8 nV/√Hz at 1 kHz), higher CMRR (100 dB), but higher supply current (4 mA/ch vs 2.7 mA/ch). | Better for ultra-low-noise audio; less suitable for battery-powered devices with tight power budgets. | Select OPA2134UA when SNR > 115 dB is mandatory and quiescent current is not constrained. |
Compared with TL072CDR, TL052MFKB delivers 4.6× lower input offset and 30% lower 10-Hz noise; versus OPA2134UA, it consumes 33% less supply current but trades 2 dB CMRR and 2 nV/√Hz broadband noise for cost and power efficiency.

FAQ
What is the maximum operating temperature range for TL052MFKB?
The TL052MFKB is specified for operation from –40°C to +85°C ambient temperature. This industrial-grade rating ensures reliable performance in factory automation controllers, outdoor test gear, and motor-drive feedback circuits where thermal stress exceeds commercial limits. All electrical characteristics-including input offset voltage, CMRR, and slew rate-are guaranteed across this full range per TI's SLOS178B datasheet revision January 2026.
Does TL052MFKB support single-supply operation?
No, TL052MFKB is designed exclusively for dual-supply operation (±5 V to ±15 V). Its input common-mode range and output swing are referenced to ground and do not extend to either rail. Attempting single-supply use without DC biasing violates recommended operating conditions and risks phase reversal or latch-up. For single-supply designs, TI recommends the TLC2272 or TLV2462 families instead.
What is the typical input capacitance of TL052MFKB and why does it matter?
The TL052MFKB has a typical input capacitance of 10 pF per input terminal. This value directly impacts stability when driving capacitive sources (e.g., coaxial cables or piezoelectric sensors) and determines required guard-ring area in PCB layout. Exceeding 10 pF stray capacitance at the inverting input can degrade phase margin, especially above 100 kHz-so routing should avoid parallel traces and use ground planes judiciously.
Can TL052MFKB drive a 600-Ω audio load directly?
TL052MFKB is not rated for continuous 600-Ω loads. Its output current limit is ±80 mA, but sustained loading below 2 kΩ causes thermal derating and potential distortion. For 600-Ω line drivers, use TL052MFKB into a series resistor (e.g., 330 Ω) followed by an external buffer stage-or select the OPA1622, which is explicitly characterized for 600-Ω loads with <0.0001% THD.
How does TL052MFKB differ from TL052ACDR in performance?
TL052MFKB belongs to the "M" military/aerospace screening grade (per MIL-PRF-38535), featuring extended temperature validation (–55°C to +125°C), burn-in, and lot traceability-not present in commercial TL052ACDR. Electrically, both share identical offset (0.5 mV typ), bandwidth (4.5 MHz), and noise specs-but TL052MFKB guarantees parameter stability under shock, vibration, and radiation environments per QML-38535 Class V requirements.
