Product details
Overview
TL052ACPG4 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 max input offset voltage at 25°C. It operates from ±5 V to ±15 V supplies and delivers rail-to-rail output swing into 2 kΩ loads, making it suitable for precision audio preamplification, sensor signal conditioning, and instrumentation front-ends.
For engineers reviewing the TL052ACPG4 datasheet, TL052ACPG4 pinout, TL052ACPG4 application, or TL052ACPG4 equivalent, this page provides verified electrical specifications, dual-channel pin mapping, real-world application context for high-impedance interfacing, and validated alternative options for FET-input op-amp upgrades.
Technical Context
The TL052ACPG4 uses enhanced JFET input stages with laser-trimmed offset voltage circuitry to achieve sub-millivolt DC accuracy without external nulling. Its internal compensation ensures stable unity-gain operation with ≥60° phase margin across temperature and supply variations.
It maintains full AC performance - including 106 dB crosstalk attenuation and 92 dB CMRR at 25°C - while drawing only 2.7 mA total supply current per dual amplifier at ±15 V, enabling low-power precision analog signal paths in multi-stage amplifiers and data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 0.5 mV max at 25°C - enables direct coupling in DC-critical sensor interfaces without offset calibration circuitry |
| Unity-Gain Bandwidth | 4.5 MHz - supports audio-band amplification and fast-settling active filters up to ~200 kHz |
| Slew Rate | 17.8 V/μs (±15 V) - preserves fidelity of 10 Vpp signals up to ~280 kHz without slewing distortion |
| Input Bias Current | 30 pA max at 25°C - minimizes voltage error across >10 MΩ source impedances (e.g., piezoelectric sensors) |
| CMRR | 92 dB at 25°C - rejects common-mode noise in differential transducer measurements with <0.001% error |
| Supply Current | 2.7 mA per dual amplifier at ±15 V - allows integration into power-constrained industrial modules without thermal derating |
| Output Swing | ±12.7 V into 2 kΩ (±15 V supply) - delivers full dynamic range to downstream ADCs or line drivers |
Pinout & Package
TL052ACPG4 is supplied in an 8-pin PDIP (Plastic Dual In-line Package) with 9.81 mm × 6.30 mm body size and 0.3 inch lead pitch. Pin 1 is marked by a notch or dot; orientation is top-view with notch left.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output | Amplifier A output - drives loads directly; requires no pull-up/pull-down for standard configurations |
| 1IN– | Input | Inverting input, channel A - connects to feedback network in inverting gain stages or summing junctions |
| 1IN+ | Input | Non-inverting input, channel A - used for high-Z sensor connections; guard ring recommended for leakage control |
| VCC– | Power | Negative supply rail - must be decoupled with 0.1 μF ceramic capacitor near pin for stability |
| 2IN+ | Input | Non-inverting input, channel B - independent of channel A; enables dual-path signal processing on single die |
| 2IN– | Input | Inverting input, channel B - supports separate feedback networks for each amplifier without crosstalk degradation |
| 2OUT | Output | Amplifier B output - electrically isolated from 1OUT with 106 dB crosstalk attenuation |
| VCC+ | Power | Positive supply rail - shared supply for both amplifiers; total ICC = 2.7 mA at ±15 V |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar FET-input dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CP | Higher 18 nV/√Hz noise, 3 mV max VIO, no on-chip trimming; same 4.5 MHz GBW and 13 V/μs SR | Acceptable where cost is critical and DC accuracy <1 mV not required; unsuitable for low-drift sensor front-ends | Select TL072CP only when legacy design reuse or BOM cost reduction outweighs need for sub-millivolt offset stability |
| OPA2134PA | Lower 8 nV/√Hz noise, 0.5 mV VIO, 8 MHz GBW, 20 V/μs SR; requires ±18 V max supply vs TL052ACPG4's ±15 V | Better for wideband audio or high-speed data acquisition; higher supply voltage limits use in ±12 V systems | Choose OPA2134PA when bandwidth >5 MHz or noise <9 nV/√Hz is mandatory; verify supply compatibility first |
Compared with TL072CP, TL052ACPG4 delivers tighter DC accuracy and lower noise at identical cost and footprint; versus OPA2134PA, it trades 3.5 MHz bandwidth for guaranteed ±15 V operation and broader industrial temperature support (0°C to 70°C).

FAQ
What is the maximum supply voltage rating for TL052ACPG4?
The TL052ACPG4 has an absolute maximum supply voltage rating of ±18 V. It is fully specified for reliable operation at ±5 V and ±15 V across its commercial temperature range (0°C to 70°C). Operation beyond ±15 V is possible but not characterized for parametric guarantees, and thermal dissipation must be verified per θJA = 85°C/W for the PDIP package.
Does TL052ACPG4 support single-supply operation?
TL052ACPG4 is optimized for dual-supply operation (±5 V to ±15 V) and does not include rail-to-rail input or output stages. Single-supply use requires external DC biasing of inputs to mid-supply and load termination to a virtual ground (e.g., using TI TLE2426), as its common-mode input range is limited to –11 V to +11 V at ±15 V supplies.
How does TL052ACPG4 differ from TL052CP?
TL052ACPG4 features tighter initial input offset voltage (0.5 mV max vs 3.5 mV max for TL052CP), improved temperature coefficient (23 μV/°C vs 25 μV/°C), and enhanced long-term drift (0.04 μV/month). Both share identical pinout, package, bandwidth, and slew rate, making TL052ACPG4 a drop-in upgrade for higher-precision applications.
What is the typical input capacitance of TL052ACPG4?
The TL052ACPG4 has a typical input capacitance of 10 pF per input terminal, measured at 25°C. This low value minimizes high-frequency phase shift in high-impedance sensor interfaces and supports stable operation with guard rings and PCB layout techniques described in TI SLOS178B Section 5.1.2.
Can unused channels in TL052ACPG4 be left floating?
No - unused op-amp channels in TL052ACPG4 must not be left floating. TI recommends configuring them as unity-gain voltage followers (output tied to inverting input, non-inverting input biased within common-mode range) to prevent oscillation, excessive current draw, or unpredictable output states that could couple noise into the active channel.
