Product details
Overview
TL052ACD from Texas Instruments is a dual, 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 0.5 mV typical input offset voltage at 25°C. It operates from ±5 V to ±15 V supplies and delivers precision signal conditioning in audio preamps, sensor interfaces, and instrumentation circuits requiring low noise and high input impedance.
For engineers reviewing the TL052ACD datasheet, TL052ACD pinout, TL052ACD application, or TL052ACD equivalent, key selection criteria include its FET-input architecture enabling >1 TΩ input resistance, trimmed DC performance versus TL072/TL082, dual-channel layout for space-constrained analog front-ends, and SOIC-8 packaging compatible with legacy designs.
Technical Context
The TL052ACD uses a BIFET (bipolar + JFET) process to combine high input impedance (>10¹² Ω) with robust output drive capability (±80 mA short-circuit current). Its internal offset-trimming circuitry reduces initial VIO to 0.57 mV (typ) and limits drift to 24 μV/°C over 25°C–70°C.
Designed as a direct upgrade path for TL072 and TL082, it maintains identical pinout and supply compatibility while improving ac response (4.5 MHz GBW vs. 3 MHz for TL072) and noise floor (10.8 nV/√Hz at 1 kHz), without increasing quiescent current (8.4 mA typ at ±15 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 0.57 mV (typ) at 25°C - enables <1 mV DC error in precision gain stages without external nulling |
| Unity-Gain Bandwidth | 4.5 MHz - supports stable closed-loop operation up to ~300 kHz with 15× gain before phase margin degradation |
| Slew Rate | 17.8 V/μs (±15 V) - allows full-scale 10 Vpp output at ≥1.8 MHz without distortion in voltage-follower configuration |
| Input Bias Current | 30 pA (max) at 25°C - preserves signal integrity when interfacing with >1 MΩ source impedances (e.g., piezoelectric sensors) |
| Common-Mode Input Range | –11 V to +11 V (±15 V supply) - permits rail-to-rail input operation within 2.3 V of each supply rail |
| Supply Current per Channel | 4.2 mA (typ) at ±15 V - balances low-power operation with high-speed performance for dual-channel systems |
| CMRR | 92 dB (typ) at 25°C - rejects >99.99% of common-mode interference in differential sensing applications |
Pinout & Package
TL052ACD is housed in an 8-pin SOIC (D package) with 4.90 mm × 3.90 mm body size and standard JEDEC MS-012AC footprint. The package supports surface-mount reflow and is RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output | Amplifier A output - drives loads up to ±80 mA; requires no external compensation for 10 kΩ || 100 pF |
| 1IN– | Input | Inverting input, channel A - high-impedance node sensitive to PCB leakage; guard ring recommended |
| 1IN+ | Input | Non-inverting input, channel A - accepts common-mode voltages up to ±11 V with ±15 V supplies |
| VCC– | Power | Negative supply rail - must be decoupled with 0.1 μF ceramic capacitor near pin |
| 2IN+ | Input | Non-inverting input, channel B - electrically isolated from channel A; crosstalk attenuation >106 dB |
| 2IN– | Input | Inverting input, channel B - shares same input stage topology and biasing as channel A |
| 2OUT | Output | Amplifier B output - independent output stage; no shared thermal or supply coupling with channel A |
| VCC+ | Power | Positive supply rail - connects to +15 V or +5 V; total ICC = 8.4 mA (±15 V) for both channels |
Key Features
| Feature | Design Value |
|---|---|
| On-chip offset-voltage trimming | Reduces initial VIO to ≤0.57 mV (typ), eliminating manual nulling in production test and reducing calibration time |
| FET-input architecture | Delivers >10¹² Ω input resistance and ≤30 pA input bias current, enabling accurate amplification of microvolt-level signals from high-Z sources |
| Pin-compatible upgrade path | Direct replacement for TL072 and TL082 in existing SOIC-8 layouts - no PCB changes required |
| Low 1/f noise corner | 50 nV/√Hz at 10 Hz - minimizes low-frequency drift in DC-coupled sensor signal chains (e.g., strain gauges, thermopiles) |
| Stable capacitive load drive | Supports ≥1000 pF loads with series output resistor - avoids oscillation in ADC driver and filter applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual FET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CD | Higher 18 nV/√Hz noise at 1 kHz, no on-chip offset trimming (VIO = 3.5 mV typ), 3 MHz GBW | Lower cost for non-precision AC-coupled audio; unsuitable for DC-coupled sensor front-ends requiring sub-mV offset | Select TL072CD only when budget constraints outweigh need for trimmed DC accuracy and lower noise |
| OPA2134PA | Lower 8 nV/√Hz noise, 8 MHz GBW, ±13.5 V max supply, higher 4.5 mA/channel ICC | Better suited for high-fidelity audio and wideband instrumentation; not pin-compatible - requires PCB redesign | Choose OPA2134PA when system demands wider bandwidth and lower noise, and layout revision is acceptable |
Compared with TL072CD, TL052ACD delivers tighter DC specs and lower noise at identical pinout; compared with OPA2134PA, it trades bandwidth and noise for pin compatibility and lower supply voltage range - making TL052ACD optimal for drop-in upgrades in legacy ±5 V/±15 V systems.

FAQ
What is the maximum supply voltage rating for TL052ACD?
The TL052ACD has an absolute maximum supply voltage rating of ±18 V. It is fully specified for operation at ±5 V and ±15 V, with recommended operating conditions spanning ±5 V to ±15 V. Exceeding ±18 V risks permanent damage due to junction breakdown, and operation above ±15 V may degrade long-term reliability even if within absolute ratings.
Does TL052ACD support single-supply operation?
TL052ACD is designed for dual-supply operation but can be used in single-supply configurations with proper DC biasing. Input common-mode range extends to within 2.3 V of either rail (e.g., 2.3 V to 12.7 V with +15 V supply), and output swing reaches within 1.5 V of rails. A virtual ground (e.g., TI TLE2426) is recommended to establish mid-supply reference for inputs and loads.
How does TL052ACD differ from TL052CD in terms of DC performance?
The 'A' grade TL052ACD features tighter input offset voltage specifications: 0.57 mV (typ) vs. 0.75 mV (typ) for TL052CD at 25°C, and 3.8 mV (max) over full temperature range vs. 4.5 mV for TL052CD. This reflects on-chip trimming in the 'A' variant, directly improving DC accuracy in precision gain stages and reducing calibration overhead.
Can TL052ACD drive capacitive loads without oscillation?
TL052ACD remains stable with ≤100 pF capacitive loads directly at the output. For larger loads (e.g., 1000 pF), a small series resistor (10–100 Ω) between the output and load restores phase margin. This behavior is documented in TI's SLOS178B datasheet Section 5.1.1 and confirmed by typical characteristics showing stable step response up to 500 pF with added isolation resistance.
Is TL052ACD pin-compatible with TL072 and TL082?
Yes, TL052ACD is fully pin-compatible with TL072 and TL082 in SOIC-8 (D), PDIP-8 (P), and SOP-8 (PS) packages. Pin functions match exactly: pins 1–4 and 5–8 correspond to OUT/IN–/IN+/V– and IN+/IN–/OUT/V+, respectively. This enables direct replacement without layout modification, delivering improved bandwidth, lower noise, and trimmed offset in existing designs.
