Texas Instruments TL054ACDR

Overview

TL054ACDR from Texas Instruments is a quad FET-input operational amplifier with on-chip offset-voltage trimming, 4.5 MHz unity-gain bandwidth, 17.8 V/μs slew rate (±15 V), and 10¹² Ω input resistance - designed for precision analog signal conditioning in instrumentation and sensor interfaces.

For engineers reviewing the TL054ACDR datasheet, TL054ACDR pinout, TL054ACDR application, or TL054ACDR equivalent, key selection criteria include its low 1.5 mV max input offset voltage (25°C, ±15 V), 92 dB typical CMRR, 106 dB crosstalk attenuation, and SOIC-14 package compatibility with legacy TL074/TL084 layouts.

Technical Context

The TL054ACDR uses enhanced JFET-input process technology to deliver improved DC accuracy over TL07x/TL08x families while maintaining FET-level input impedance and bipolar-like output drive. Its internal architecture includes trimmed input-stage transistors to minimize initial offset and temperature drift.

It operates across ±5 V to ±15 V dual supplies, supports rail-to-rail input common-mode range up to ±12.3 V (±15 V supply), and delivers ±12.7 V output swing into 2 kΩ at 25°C - enabling high-fidelity amplification of low-level AC signals without clipping.

FAQ

What is the maximum operating supply voltage for TL054ACDR?

The TL054ACDR supports absolute maximum supply voltages of ±18 V, but is fully specified for reliable operation across ±5 V to ±15 V dual supplies. Operation at ±15 V yields optimal performance: 17.8 V/μs slew rate, 4.5 MHz bandwidth, and ±12.7 V output swing into 2 kΩ. Exceeding ±18 V risks permanent damage per Absolute Maximum Ratings.

Does TL054ACDR support single-supply operation?

The TL054ACDR is designed for dual-supply use and does not feature rail-to-rail input or output. When used with single supplies, external DC biasing is mandatory: inputs must be referenced to mid-supply (e.g., via TLE2426 virtual ground), and output loads terminated to that same node. Its common-mode input range extends only to within ~2.3 V of either rail - limiting true single-supply utility.

How does TL054ACDR differ from TL054CDR?

The TL054ACDR features tighter DC specifications than TL054CDR: max input offset voltage is 1.5 mV (vs. 4 mV) and temperature coefficient is 23 μV/°C (vs. 25 μV/°C) at ±15 V, 25°C. Both share identical SOIC-14 packaging, pinout, bandwidth, and slew rate - making TL054ACDR the preferred choice for high-precision applications demanding lower initial offset and drift.

What is the input capacitance of TL054ACDR?

The TL054ACDR has a typical input capacitance of 10 pF per amplifier input, as measured at 25°C. This low value minimizes phase shift and instability when driving capacitive sources or when used in high-frequency filter topologies. Combined with 10¹² Ω input resistance, it forms a 1.6 MHz RC pole - well above its 4.5 MHz unity-gain bandwidth, ensuring stable high-frequency behavior.

Can TL054ACDR drive heavy capacitive loads?

The TL054ACDR can drive capacitive loads up to 1000 pF when a small series resistance (e.g., 10–100 Ω) is added at the output to isolate the amplifier from the load capacitance. Without isolation, loads >100 pF may cause peaking or oscillation due to phase margin degradation. The device's phase margin is 60° at unity gain with 25 pF load - confirming stability under typical PCB trace and probe conditions.
