Texas Instruments TLE2071ACDR

Overview

TLE2071ACDR from Texas Instruments is a single-channel, JFET-input operational amplifier optimized for high-voltage, low-noise, high-speed precision applications. It delivers ±300 µV typical input offset voltage, 17 nV/√Hz input voltage noise at 1 kHz, 10 MHz unity-gain bandwidth, ±19 V supply capability, and operates across 0°C to 70°C. It serves as a signal-conditioning front-end in digital multimeters and oscilloscope analog acquisition stages.

For engineers reviewing the TLE2071ACDR datasheet, TLE2071ACDR pinout, TLE2071ACDR application, or TLE2071ACDR equivalent, key selection criteria include its rail-to-rail input operation, low bias current (±15 pA), wide common-mode range (±11.9 V at ±15 V supplies), and SOIC-8 packaging with tape-and-reel delivery for automated assembly.

Technical Context

The TLE2071ACDR employs Excalibur JFET-input architecture with on-chip Zener trimming for DC precision, enabling stable operation with differential inputs extending to the supply rails. Its 32 V/µs slew rate and 10.6 MHz unity-gain bandwidth support fast settling (0.25 µs to 10 mV) in closed-loop configurations up to 300 kHz output-swing bandwidth.

Designed for ±2.25 V to ±19 V dual-supply operation, it achieves 98 dB CMRR and 99 dB supply-voltage rejection at 25°C under ±15 V conditions, with input resistance exceeding 6 TΩ and input capacitance of 9 pF (differential), making it suitable for high-impedance sensor interfacing and precision integrator circuits.

FAQ

What is the operating temperature range for the TLE2071ACDR?

The TLE2071ACDR is rated for an operating free-air temperature range of 0°C to 70°C (C-suffix grade). This is confirmed in Table 4-1 and Section 6.2 of the TI datasheet, where "TLE2071ACD" and "TLE2071ACDR" share identical thermal specifications. The R suffix denotes tape-and-reel packaging only and does not alter thermal ratings. Full-range electrical characteristics are guaranteed across this interval.

Does the TLE2071ACDR support rail-to-rail input operation?

Yes, the TLE2071ACDR supports rail-to-rail input operation: its common-mode input voltage range extends to (V−) − 0.5 V and (V+) + 0.5 V, as specified in Section 6.1 Absolute Maximum Ratings and verified in Table 6.5 (VICR = −11.9 V to +11.9 V at ±15 V supplies). This allows direct interfacing with signals near supply rails without phase inversion or clipping, a key feature distinguishing it from standard BJT-input op-amps.

What is the purpose of Pins 1 and 5 on the TLE2071ACDR?

Pins 1 and 5 on the TLE2071ACDR are offset null terminals (N1 and N2) used to minimize input offset voltage via an external 10-kΩ potentiometer connected between them, with the wiper grounded. This adjustment is supported in all TLE2071 variants per Figure 5-1 and Section 6.3, and is especially valuable in DC-critical applications like precision metering where initial VIO must be trimmed below 100 µV.

Is the TLE2071ACDR unity-gain stable?

Yes, the TLE2071ACDR is unity-gain stable, with a phase margin of 56°–57° at unity gain (Section 6.4/6.6/6.8/6.10), and a unity-gain bandwidth of 10.6 MHz (typical) confirmed across all supply and temperature conditions. Its internal compensation ensures stable operation in follower, inverter, and active filter configurations without external compensation components.

How does the TLE2071ACDR differ from the TLE2071CDR?

The TLE2071ACDR features tighter DC specifications than the TLE2071CDR: its maximum input offset voltage is 2 mV (vs. 4 mV for CDR), and its typical offset is ±0.3 mV (vs. ±0.34 mV for CDR), as shown in Table 4-1 and Section 6.3. Both share identical AC performance (10.6 MHz GBW, 32 V/µs slew rate), package (SOIC-8), and pinout-but the "A" grade provides enhanced precision for applications demanding lower initial error and drift.
