Product details
Overview
TL052ACDR 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 serves as a precision upgrade to TL072/TL082 in high-impedance sensor interfaces and audio signal conditioning circuits.
For engineers reviewing the TL052ACDR datasheet, TL052ACDR pinout, TL052ACDR application, or TL052ACDR equivalent, key selection criteria include its FET-input architecture enabling >1 TΩ input resistance, low 10.8 nV/√Hz input voltage noise at 1 kHz, and guaranteed crosstalk attenuation of 106 dB between channels - critical for dual-channel instrumentation and differential signal processing.
Technical Context
The TL052ACDR uses a JFET-input front-end with on-chip laser-trimmed offset compensation, delivering improved DC accuracy over TL072/TL082 while maintaining full pin compatibility. Its enhanced FET process yields higher slew rate and bandwidth without increasing quiescent current - 2.7 mA typical supply current per dual amplifier at ±15 V.
Designed for dual-supply operation, it specifies common-mode input range from –12.3 V to +15.1 V (±15 V) and output swing to within 1.1 V of rails into 2 kΩ. Input bias current remains below 0.2 nA at 85°C, supporting stable operation with high-impedance sources like piezoelectric sensors and photodiode transimpedance stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 0.5 mV typ at 25°C - enables <100 μV error in 100× gain stages without external nulling |
| Unity-Gain Bandwidth | 4.5 MHz - supports stable closed-loop operation up to ~400 kHz with 10× gain |
| Slew Rate | 17.8 V/μs (±15 V) - allows full-scale 10 Vpp output at 280 kHz without distortion |
| Input Voltage Noise | 10.8 nV/√Hz at 1 kHz - lower than TL072 (18 nV/√Hz), critical for low-level audio preamps |
| Crosstalk Attenuation | 106 dB - ensures channel isolation >200,000:1 in dual-channel active filters |
| Common-Mode Rejection | 92 dB min (±15 V) - maintains accuracy when rejecting power-supply ripple in single-ended sensor outputs |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output | Amplifier 1 output - drives loads ≥2 kΩ; rail-to-rail swing not supported |
| 1IN– | Input | Inverting input, channel 1 - high-impedance node requiring guard ring for leakage control |
| 1IN+ | Input | Non-inverting input, channel 1 - accepts common-mode voltages up to ±12.3 V (±15 V) |
| VCC– | Power | Negative supply rail - must be connected to system ground or negative rail; no internal ESD diode to GND |
| 2IN+ | Input | Non-inverting input, channel 2 - electrically isolated from channel 1; 106 dB crosstalk spec applies |
| 2IN– | Input | Inverting input, channel 2 - shares same input stage topology and noise performance as channel 1 |
| 2OUT | Output | Amplifier 2 output - independent output stage; supports simultaneous dual-channel operation |
| VCC+ | Power | Positive supply rail - requires decoupling capacitor ≤10 cm from pin per TI layout guidelines |
Key Features

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 18 nV/√Hz input noise, 3 mV typical VIO, no on-chip offset trim | Lower cost; acceptable where noise <15 nV/√Hz and offset <3 mV are tolerable | Choose TL072CDR only if budget constraints outweigh need for low-noise/low-offset performance |
| OPA2134PA | 12 V/μs slew rate, 8 MHz GBW, 8 nV/√Hz noise, ±18 V absolute max rating | Wider supply range and superior noise performance; requires PCB layout changes due to different pinout | Choose OPA2134PA for demanding audio or precision measurement where layout revision is feasible |

FAQ
What is the maximum supply voltage rating for TL052ACDR?
The TL052ACDR 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 limiting VCC± to ±15 V maximum for reliable long-term performance. Exceeding ±18 V risks permanent damage per the Absolute Maximum Ratings table in the datasheet.
Does TL052ACDR support single-supply operation?
TL052ACDR is designed for dual-supply operation and does not feature rail-to-rail input or output. When used with single supplies, DC biasing of inputs to mid-rail and use of a virtual ground (e.g., TI TLE2426) are required to stay within common-mode and output swing limits. Its specified VICR is –12.3 V to +15.1 V at ±15 V, not referenced to GND.
How does TL052ACDR differ from TL052CDR?
TL052ACDR features tighter initial input offset voltage (0.5 mV typ vs. 0.65 mV typ for TL052CDR), improved temperature coefficient (23 μV/°C vs. 25 μV/°C), and guaranteed performance across the full commercial temperature range (0°C to 70°C). The 'A' grade reflects enhanced DC precision trimming and extended characterization.
What is the input capacitance of TL052ACDR and why does it matter?
TL052ACDR has 10 pF typical input capacitance per input terminal. This value impacts stability in high-impedance feedback networks and high-frequency applications - particularly when driving capacitive loads or using guard rings. Layout best practices require minimizing stray capacitance at IN+ and IN– nodes to preserve phase margin and prevent oscillation.
Can TL052ACDR drive a 600 Ω audio load directly?
No, TL052ACDR is not rated to drive 600 Ω loads continuously. Its output stage is specified for RL ≥ 2 kΩ; driving 600 Ω risks thermal overload and output swing degradation. For 600 Ω line-driving applications, use a dedicated audio line driver (e.g., BUF634) or add a series resistor + external buffer stage to maintain signal integrity and device reliability.
