Product details
Overview
TL052CDRG4 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, and ±15 V supply capability. It delivers enhanced DC precision and AC performance over TL072/TL082 while maintaining pin compatibility for drop-in upgrades in audio preamps, sensor signal conditioning, and instrumentation circuits.
For engineers reviewing the TL052CDRG4 datasheet, TL052CDRG4 pinout, TL052CDRG4 application, or TL052CDRG4 equivalent, key selection criteria include input offset voltage (≤1.5 mV max at ±15 V), low 10.8 nV/√Hz input voltage noise at 1 kHz, high 10¹² Ω input resistance, and dual-channel SOIC-8 packaging suitable for space-constrained analog front-ends.
Technical Context
The TL052CDRG4 uses a JFET-input stage to achieve ultra-low input bias current (≤200 pA at 25°C) and high input impedance, enabling accurate amplification of high-impedance sources like piezoelectric sensors and photodiode transimpedance stages. Its trimmed offset and low drift (23 μV/°C) support stable DC-coupled gain stages without frequent recalibration.
Designed for dual-supply operation, it specifies full performance across ±5 V to ±15 V rails, with common-mode input range extending to within 2.3 V of either rail and output swing to within 1.1 V of rails under 2 kΩ load - critical for wide-dynamic-range signal processing in test equipment and data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±5 V to ±15 V - supports both low-voltage portable designs and industrial ±15 V legacy systems |
| Input Offset Voltage | ≤1.5 mV (max, ±15 V, 25°C) - enables accurate DC amplification without external nulling circuitry |
| Unity-Gain Bandwidth | 4.5 MHz - sufficient for audio band (20 Hz–20 kHz) with >100 dB open-loop gain margin |
| Slew Rate | 17.8 V/μs (positive), 15.9 V/μs (negative) - supports clean 10 Vpp signals up to ~280 kHz without distortion |
| Input Voltage Noise | 10.8 nV/√Hz at 1 kHz - lower than TL082 (18 nV/√Hz), critical for low-level sensor interfacing |
| Common-Mode Rejection | ≥92 dB (typ, ±15 V) - rejects power supply ripple and ground noise in differential configurations |
| Input Resistance | 10¹² Ω - preserves signal integrity from megohm-range sources like pH electrodes and capacitive sensors |
Pinout & Package
TL052CDRG4 is supplied in an 8-pin SOIC (D package) with 4.90 mm × 3.90 mm body size and standard JEDEC MS-012AC footprint. Pin 1 is channel 1 output; pins 2 and 3 are inverting/non-inverting inputs for channel 1; pin 4 is VCC–; pins 5 and 6 are non-inverting/inverting inputs for channel 2; pin 7 is channel 2 output; pin 8 is VCC+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output | Amplified output signal from first op-amp channel - drives loads up to 80 mA |

| 1IN+ | Input | Non-inverting input of channel 1 - connects to high-impedance signal sources with minimal loading |
| VCC– | Power | Negative supply rail - must be decoupled with ≥0.1 μF ceramic capacitor near pin |
| 2IN+ | Input | Non-inverting input of channel 2 - electrically isolated from channel 1 for dual independent signal paths |
| 2IN– | Input | Inverting input of channel 2 - supports differential pair or active filter topologies |
| 2OUT | Output | Amplified output signal from second op-amp channel - shares no internal coupling with 1OUT |
| VCC+ | Power | Positive supply rail - requires symmetric decoupling to VCC– for optimal PSRR performance |

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; no on-chip offset trimming (VIO ≤6 mV); 3 MHz bandwidth | Acceptable where cost sensitivity outweighs precision requirements; unsuitable for sub-mV DC accuracy | Choose TL072CDR only when budget constraints preclude TL052CDRG4 and noise/offset specs are relaxed |
| OPA2134PA | Lower 8 nV/√Hz noise; higher 8 MHz bandwidth; ±18 V rating; SO-8 package but not pin-compatible | Requires PCB redesign; preferred for high-fidelity audio or wideband sensor systems needing >4.5 MHz response | Select OPA2134PA when upgrading system performance justifies layout revision and higher BOM cost |
Compared with TL072CDR, TL052CDRG4 provides tighter offset control and lower noise for precision DC-coupled stages; compared with OPA2134PA, it offers drop-in replacement capability at lower cost but trades bandwidth and ultimate noise performance.

FAQ
What is the maximum supply voltage rating for TL052CDRG4?
The TL052CDRG4 has an absolute maximum supply voltage rating of ±18 V, with recommended operating range from ±5 V to ±15 V. Operation at ±15 V is fully characterized across 0°C to 70°C ambient, delivering specified performance for input offset voltage (≤1.5 mV), slew rate (17.8 V/μs), and output swing (±13.9 V into 10 kΩ). Exceeding ±18 V risks permanent device damage per TI's Absolute Maximum Ratings table.
Does TL052CDRG4 support single-supply operation?
The TL052CDRG4 is designed for dual-supply operation and is not characterized for true single-supply use. When operated from a single rail, DC biasing of inputs to mid-supply and use of a virtual ground (e.g., TI TLE2426) are mandatory to stay within common-mode input voltage limits (–11 V to +11 V at ±15 V supplies). TI explicitly recommends LinCMOS TLC-series op-amps for native single-supply applications.
What is the input bias current specification for TL052CDRG4 at 70°C?
At 70°C and ±15 V supply, the TL052CDRG4 exhibits a maximum input bias current of 4 nA per input, as specified in Section 4.4 of the SLOS178B datasheet. This value reflects worst-case behavior across process variation and temperature - significantly lower than bipolar-input op-amps (typically >100 nA), making TL052CDRG4 suitable for high-impedance sensor interfaces where leakage would otherwise dominate error budgets.
Is TL052CDRG4 pin-compatible with TL082CP?
Yes, TL052CDRG4 is fully pin-compatible with TL082CP in the 8-pin PDIP package and with TL082CDR in SOIC-8. Pin functions match exactly: pins 1–4 and 5–8 serve identical roles (1OUT, 1IN–, 1IN+, VCC–, 2IN+, 2IN–, 2OUT, VCC+). This allows direct replacement in existing PCB layouts without modification - a core design goal confirmed in TI's Description section and Pin Configuration documentation.
What is the typical crosstalk attenuation between channels in TL052CDRG4?
The TL052CDRG4 provides typical crosstalk attenuation of 106 dB between its two independent amplifier channels, measured under unity-gain conditions with AVD = 100. This high isolation level ensures minimal signal coupling - critical in dual-path applications such as stereo audio buffering or differential sensor pairs - and is verified across both ±5 V and ±15 V supply conditions per Section 4.4 Electrical Characteristics.
