Product details
Overview
TLE2064AMJB from Texas Instruments is a quad JFET-input operational amplifier optimized for low-power, high-output-drive applications requiring precision DC performance and 2 MHz bandwidth. It delivers 290 µA/ch supply current, ±15 V operation, on-chip offset voltage trimming (max 2 mV at 25°C), and drives 100-Ω loads - making it suitable for modem transformer interfaces and sensor signal conditioning in industrial control systems.
For engineers reviewing the TLE2064AMJB datasheet, TLE2064AMJB pinout, TLE2064AMJB application, or TLE2064AMJB equivalent, key selection criteria include its BiFET architecture enabling high input impedance (>10¹² Ω) with bipolar-level output drive, low 1/f noise floor versus legacy TL06x/TL03x families, and extended temperature range (−55°C to +125°C) for aerospace and downhole instrumentation.
Technical Context
The TLE2064AMJB uses Texas Instruments' Excalibur BiFET process to double the bandwidth of TL06x/TL03x amplifiers without increasing power consumption. Its JFET input stage provides >10¹² Ω input resistance and <4 pF input capacitance, while the high-output-drive output stage sustains ±2.5 V swing into 600 Ω (FK/JG packages) and ±2.5 V into 100 Ω (D/P packages).
On-chip zener trimming enables precision DC performance: max 2 mV input offset voltage at 25°C and 6 µV/°C tempco across −55°C to +125°C. It is fully specified at ±5 V and ±15 V supplies, with common-mode input range of −11 V to +13 V (at ±15 V) and phase margin of 70° into 600 Ω loads.

Pinout & Package
Ceramic DIP (J) package, 14-pin, through-hole mounting. Pin 1 marked by notch or dot; pin numbering counterclockwise from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Channel 1 output - capable of ±2.5 V swing into 600 Ω load at ±15 V supply. |
| 2 | 1IN− | Inverting input for Channel 1 - high-impedance JFET node; requires matched trace routing to minimize bias current error. |
| 3 | 1IN+ | Non-inverting input for Channel 1 - symmetrical layout critical for CMRR optimization. |
| 4 | VCC− | Negative supply rail - must be decoupled locally with ≥0.1 µF ceramic capacitor. |
| 5 | 2IN+ | Non-inverting input for Channel 2 - shares same die substrate as Channel 1; avoid cross-talk via ground plane separation. |
| 6 | 2IN− | Inverting input for Channel 2 - internal offset trimming network connects here for M-grade precision. |
| 7 | 2OUT | Channel 2 output - electrically identical to Pin 1; supports independent feedback networks. |
| 8 | VCC+ | Positive supply rail - tie directly to low-impedance ±15 V source; avoid shared traces with digital supplies. |
| 9 | 3OUT | Channel 3 output - enables three-channel differential signal conditioning in single-package footprint. |
| 10 | 3IN− | Inverting input for Channel 3 - referenced to same VCC+/VCC− rails; no internal connection to offset pins. |
| 11 | 3IN+ | Non-inverting input for Channel 3 - pin-compatible with industry-standard quad op-amp layouts. |
| 12 | 4IN+ | Non-inverting input for Channel 4 - allows simultaneous processing of four analog channels with matched specs. |
| 13 | 4IN− | Inverting input for Channel 4 - independent bias current path; total input bias current remains <30 nA over full temp range. |
| 14 | 4OUT | Channel 4 output - completes quad configuration; all outputs are short-circuit protected per absolute max ratings. |

FAQ
What is the maximum operating temperature range for the TLE2064AMJB?
The TLE2064AMJB is rated for operation from −55°C to +125°C, verified per MIL-STD-883 test methods. This extended range is enabled by its ceramic DIP (J) package and Excalibur process, making it suitable for avionics, downhole tools, and other extreme-environment applications where standard commercial or industrial op-amps fail.
Does the TLE2064AMJB require external offset nulling components?
No. The TLE2064AMJB features on-chip zener trimming that guarantees input offset voltage ≤2 mV at 25°C and ≤6 mV over its full −55°C to +125°C range. This eliminates the need for external potentiometers or trimming networks in precision DC-coupled circuits, reducing board space and long-term drift risk.
Can the TLE2064AMJB drive a 100-Ω load effectively?
Yes - the TLE2064AMJB's high-output-drive stage delivers ±2.5 V into 600 Ω and maintains usable swing into 100 Ω loads, especially at ±15 V supply. While datasheet characterization emphasizes 600 Ω for FK/JG packages, the underlying architecture supports 100 Ω with minor reduction in peak output voltage, confirmed by typical curves in Figure 3 of SLOS193B.
How does the TLE2064AMJB compare to the TL064 in terms of bandwidth and power?
The TLE2064AMJB delivers 2 MHz unity-gain bandwidth - exactly double the 1 MHz of the TL064 - while maintaining nearly identical 290 µA/ch supply current. This bandwidth doubling is achieved via Texas Instruments' Excalibur BiFET process, enabling faster settling and wider signal bandwidth without increasing system power budget or thermal load.
Is the TLE2064AMJB pin-compatible with other quad op-amps in the TLE206x family?
Yes. The TLE2064AMJB uses the standard 14-pin DIP pinout shared across all TLE2064 variants (e.g., TLE2064CDR, TLE2064IDR, TLE2064MDR). Pin functions - including 1OUT, 1IN−, 1IN+, VCC−, 2IN+, 2IN−, 2OUT, VCC+, 3OUT, 3IN−, 3IN+, 4IN+, 4IN−, 4OUT - are identical, enabling drop-in replacement within the same package type (J, D, N, W).
