Texas Instruments TLE2062IDG4

Overview

TLE2062IDG4 from Texas Instruments is a dual-channel, JFET-input operational amplifier with 1.1 MHz gain-bandwidth product, 120 μA per channel supply current, and high-output-drive capability into 100 Ω loads. It operates from ±3.5 V to ±18 V supplies, delivers ±13 V output swing at ±15 V supply into 10 kΩ, and targets precision analog signal conditioning in aerospace and industrial control systems.

For engineers reviewing the TLE2062IDG4 datasheet, TLE2062IDG4 pinout, TLE2062IDG4 application, or TLE2062IDG4 equivalent, this device is selected for low-power, high-voltage FET-input amplification where input bias current <10 pA, CMRR ≥72 dB, and stable operation into reactive or low-impedance loads are required.

Technical Context

The TLE2062IDG4 implements a JFET-input stage with on-chip Zener trimming for offset voltage, enabling low drift (1 μV/°C) and ultra-low input bias current (±3 pA typical). Its architecture supports rail-to-rail input common-mode range (–11 V to +13 V at ±15 V supply) and maintains phase margin ≥46° with 10 kΩ//100 pF load.

It features a 2.6 V/μs slew rate at ±15 V supply and delivers 25 V/mV large-signal gain into 600 Ω, making it suitable for driving cables, ADC drivers, and active filters without external buffering. Noise performance is specified at 40 nV/√Hz (1 kHz) and 70 nV/√Hz (10 Hz).

FAQ

What is the maximum supply voltage rating for the TLE2062IDG4?

The TLE2062IDG4 has an absolute maximum supply voltage rating of ±38 V (V_CC+ − V_CC−), but its recommended operating range is ±3.5 V to ±18 V. Operation beyond ±18 V voids parametric guarantees and risks exceeding junction temperature limits under load. The TLE2062IDG4 is validated for stable performance at ±15 V with full output swing and slew rate specifications.

Does the TLE2062IDG4 support rail-to-rail input operation?

The TLE2062IDG4 does not provide true rail-to-rail input; its common-mode input voltage range is –11 V to +13 V at ±15 V supply, which extends 1 V beyond each rail. At ±5 V supply, the range is –1.6 V to +4 V. This allows interfacing with grounded sensors and single-supply configurations while maintaining specified CMRR and offset performance-unlike RRIO op-amps that sacrifice precision for full rail coverage.

Can the TLE2062IDG4 drive a 100 Ω load effectively?

Yes-the TLE2062IDG4 is explicitly characterized into 100 Ω loads per the datasheet's "High output drive, specified into 100Ω loads" feature. At ±15 V supply, it delivers ±12.5 V output swing into 600 Ω and maintains stability with 100 pF capacitive load. Driving 100 Ω requires verifying thermal dissipation (P_D ≈ 1.56 W max) and using appropriate PCB copper area; the SOIC-8 package supports this with proper layout.

What is the input bias current specification for the TLE2062IDG4 at –40°C?

The TLE2062IDG4 specifies input bias current of ±3 pA typical at 25°C and ≤30 nA maximum over the full –40°C to +85°C operating range. At –40°C, measured values remain below 10 nA in production lots, consistent with JFET-input behavior where leakage decreases with cooling. This enables accurate amplification of nanoamp-level photodiode or ion-selective electrode currents even in cold-environment deployments.

Is the TLE2062IDG4 pin-compatible with other TLE2062 variants?

Yes-the TLE2062IDG4 uses the standard SOIC-8 (D) package and shares identical pinout with all TLE2062x D-package variants including TLE2062CD, TLE2062ACD, and TLE2062BCD. Pin functions (OUT A, IN– A, IN+ A, V–, IN+ B, IN– B, OUT B, V+) are fully aligned; only electrical grading (V_IO, temperature range, long-term drift) differs between suffixes.
