Texas Instruments TLE2037IDR

Overview

TLE2037IDR from Texas Instruments is a decompensated, high-speed precision operational amplifier optimized for closed-loop gains ≥5. It delivers 50 MHz gain-bandwidth product, 7.5 V/μs slew rate, and ultra-low 2.5 nV/√Hz input voltage noise at 1 kHz - enabling high-fidelity signal conditioning in test equipment front-ends and precision data acquisition systems.

For engineers reviewing the TLE2037IDR datasheet, TLE2037IDR pinout, TLE2037IDR application, or TLE2037IDR equivalent, key selection criteria include its −40°C to 105°C industrial temperature rating, D-package SOIC-8 footprint, decompensated stability requirement (AV ≥ 5), and low-noise performance at audio-to-RF frequencies.

Technical Context

The TLE2037IDR uses TI's Excalibur bipolar process to achieve simultaneous dc precision and ac speed. Its decompensated internal architecture enables 50 MHz GBW and 7.5 V/μs slew rate but mandates minimum closed-loop gain of 5 for phase-margin stability (50°). Input stage features matched transistors yielding 25 μV max input offset voltage and 131 dB typical CMRR.

It integrates saturation recovery circuitry to minimize overload recovery time, supports ±4 V to ±19 V dual supply operation, and maintains 11 V output swing into 2 kΩ load at ±15 V supplies. Noise performance is specified with 20 Ω source impedance per Figure 2 of SLOS192C.

FAQ

Is the TLE2037IDR unity-gain stable?

No, the TLE2037IDR is decompensated and requires a minimum closed-loop gain of 5 for stable operation. Attempting unity-gain configuration results in oscillation due to insufficient phase margin (50° at unity gain). For AV = 1 applications, consider alternatives like OPA1611AID or AD8021ARMZ.

What is the maximum output voltage swing of the TLE2037IDR at ±15 V supplies?

At ±15 V supplies and 25°C, the TLE2037IDR delivers ±13.2 V maximum positive/negative peak output swing into a 2 kΩ load, and ±12.9 V into a 600 Ω load. Output swing decreases with increasing temperature and load current per the VOM+/VOM− specifications in the TLE20x7I electrical characteristics table.

Does the TLE2037IDR support single-supply operation?

Yes, the TLE2037IDR operates with split or single supplies within ±4 V to ±19 V total range (i.e., 8 V to 38 V). For single-supply use, bias the inputs within the common-mode range (e.g., VIC = VCC+/2) and reference output appropriately; note that output swing does not rail-to-rail.

How is offset voltage trimmed on the TLE2037IDR?

The TLE2037IDR provides two offset null terminals (Pins 1 and 5). Connect a 10 kΩ potentiometer between them, with wiper to VCC−, to adjust input offset voltage to ≤10 μV. This trimming is effective across temperature and improves system-level accuracy without external calibration hardware.

What is the recommended PCB layout practice for minimizing noise in TLE2037IDR circuits?

Use local 0.1 μF ceramic decoupling capacitors directly at Pins 4 (VCC−) and 7 (VCC+), keep input traces short and symmetrical, route high-impedance nodes away from digital switching areas, and ground the exposed pad (if present) to minimize thermal resistance and noise coupling - though the SOIC-8 D package has no exposed pad.
