Product details
Overview
TL052CDR from Texas Instruments is a dual JFET-input operational amplifier engineered for precision analog signal conditioning in dual-supply systems. It delivers 4.5 MHz unity-gain bandwidth, 17.8 V/μs positive slew rate (±15 V), and 0.65 mV max input offset voltage at 25°C - enabling high-fidelity amplification of low-level sensor signals with minimal DC error. It is used in instrumentation front-ends, active filters, and audio preamplifier stages requiring low noise and high input impedance.
For engineers reviewing the TL052CDR datasheet, TL052CDR pinout, TL052CDR application, or TL052CDR equivalent, this page provides verified electrical specifications, SOIC-8 package details, dual-channel pin mapping, and validated alternatives for precision FET op-amp replacement in industrial and test equipment designs.
Technical Context
The TL052CDR implements a JFET-input differential pair architecture optimized for low input bias current (≤200 pA at 25°C) and enhanced DC stability via on-chip offset-voltage trimming. Its design improves upon TL07x/TL08x families by delivering higher slew rate and bandwidth without increasing quiescent current - maintaining 8.4 mA typical supply current at ±15 V.
It operates across ±5 V to ±15 V supplies, supports common-mode input ranges up to ±11 V (at ±15 V), and achieves 92 dB typical CMRR and 99 dB typical PSRR at 25°C - making it suitable for high-rejection signal conditioning where power supply noise and common-mode interference must be suppressed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 4.5 MHz - enables stable closed-loop operation up to audio frequencies with minimal phase lag. |
| Input offset voltage (max) | 0.65 mV at 25°C - ensures ≤0.65 mV DC error in precision gain stages without external nulling. |
| Slew rate (positive) | 17.8 V/μs at ±15 V - supports fast transient response in pulse amplification and active filter applications. |
| Input bias current (max) | 200 pA at 25°C - preserves signal integrity when interfacing with high-impedance sources (>1 MΩ). |
| Common-mode rejection ratio | 92 dB typical - rejects >99.99% of common-mode interference in differential sensing configurations. |
| Supply voltage range | ±5 V to ±15 V - compatible with standard dual-rail lab and industrial power supplies. |
| Equivalent input noise (1 kHz) | 10.8 nV/√Hz - maintains signal-to-noise ratio in low-level transducer amplification (e.g., piezoelectric sensors). |
Pinout & Package
TL052CDR is housed in an 8-pin SOIC (D) package measuring 4.90 mm × 3.90 mm, with standard JEDEC MS-012AC footprint and 1.27 mm lead pitch. The package supports automated assembly and meets IPC-7351B Class B requirements for industrial PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output | Amplified output signal from Channel 1 - drives loads ≥2 kΩ with ±11.5 V swing (±15 V supply). |
| 1IN– | Input | Inverting input of Channel 1 - forms feedback node in inverting amplifier or differential configuration. |
| 1IN+ | Input | Non-inverting input of Channel 1 - accepts high-impedance sensor signals with <200 pA loading. |
| VCC– | Power | Negative supply rail - must be connected to stable −5 V to −15 V reference; not internally tied to substrate. |
| 2IN+ | Input | Non-inverting input of Channel 2 - electrically isolated from Channel 1; supports independent dual-path signal chains. |
| 2IN– | Input | Inverting input of Channel 2 - enables matched dual instrumentation amplifier topologies with shared gain resistors. |
| 2OUT | Output | Amplified output signal from Channel 2 - exhibits 106 dB crosstalk attenuation relative to Channel 1 output. |
| VCC+ | Power | Positive supply rail - must be connected to stable +5 V to +15 V reference; decoupling capacitor required. |
Key Features
| Feature | Design Value |

| On-chip offset-voltage trimming | Reduces initial VIO to ≤0.65 mV (C-grade), eliminating manual nulling circuitry in production systems. |
| FET-input architecture | Delivers 10¹² Ω input resistance and ≤200 pA bias current - critical for photodiode, pH probe, and strain gauge interfaces. |
| Pin-compatible upgrade path | Direct drop-in replacement for TL072 and TL082 in existing PCBs - no layout changes required. |
| Low 1/f noise corner | 50 nV/√Hz at 10 Hz - preserves signal fidelity in sub-audio measurement applications (e.g., seismic sensors). |
| Stable unity-gain operation | 60° phase margin with 25 pF load - ensures unconditional stability without external compensation in follower configurations. |

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 10.8 nV/√Hz noise floor at 1 kHz; 1.5 mV max VIO; no on-chip trimming. | Acceptable for non-critical AC-coupled audio paths but unsuitable for DC-stable sensor front-ends. | Select TL052CDR when VIO ≤0.65 mV and long-term drift <0.04 μV/month are required. |
| OPA2134PA | Lower 8 nV/√Hz noise; 0.5 mV max VIO; rail-to-rail output; higher 8 MHz GBW. | Requires single-supply redesign; incompatible pinout; higher cost per channel. | Choose OPA2134PA only if rail-to-rail output swing and sub-8 nV/√Hz noise justify layout change and BOM cost increase. |
Compared with TL072CDR, TL052CDR offers tighter DC specs and lower noise without sacrificing SOIC-8 compatibility; versus OPA2134PA, it retains legacy dual-supply support and lower unit cost while trading off rail-to-rail output and marginal noise improvement.

FAQ
What is the maximum supply voltage rating for TL052CDR?
The TL052CDR has an absolute maximum supply voltage rating of ±18 V. However, it is fully specified and characterized for reliable operation within ±5 V to ±15 V. Operating beyond ±15 V may exceed guaranteed performance limits for parameters such as input offset voltage, CMRR, and output swing - always refer to Section 4.1 Absolute Maximum Ratings in the official datasheet for thermal and reliability boundaries.
Does TL052CDR support single-supply operation?
TL052CDR is designed for dual-supply operation and does not feature rail-to-rail input or output. When used with single supplies, DC biasing of both inputs to mid-rail and termination of loads to a virtual ground (e.g., using TI's TLE2426) is mandatory. Input common-mode range is limited to –1 V to +4 V at ±5 V supplies - violating this range risks phase reversal or latch-up.
How does TL052CDR differ from TL082 in practical circuit design?
TL052CDR improves upon TL082 with lower input offset voltage (0.65 mV vs. 15 mV max), lower noise (10.8 nV/√Hz vs. 18 nV/√Hz), and higher slew rate (17.8 V/μs vs. 13 V/μs). Unlike TL082, TL052CDR uses on-chip trimming for DC stability - reducing need for external nulling pots in production systems while maintaining identical SOIC-8 pinout and footprint.
What is the typical input capacitance of TL052CDR?
The TL052CDR has a typical input capacitance of 10 pF per input terminal, as measured at 25°C. This value remains stable across temperature and supply voltage - critical for high-frequency stability analysis in transimpedance or capacitive-sensor amplifier designs where stray capacitance directly impacts bandwidth and phase margin.
Can unused channels in TL052CDR be left floating?
No - unused channels in TL052CDR must not be left floating. Per TI's application guidance, each unused amplifier should be configured as a unity-gain buffer with its non-inverting input tied to a stable reference (e.g., mid-supply via resistor divider) and output connected to its inverting input. Floating inputs risk oscillation, increased supply current, or unpredictable output states that may disrupt adjacent channels.
