Product details
Overview
TLE2064IN from Texas Instruments is a quad FET-input operational amplifier with 36V supply capability, 1.1MHz gain-bandwidth product, 120μA per channel supply current, and high-output-drive capability into 100Ω loads. It serves as a precision, low-power signal conditioning amplifier in industrial analog input modules and flight control units where wide voltage range and low noise are critical.
For engineers reviewing the TLE2064IN datasheet, TLE2064IN pinout, TLE2064IN application, or TLE2064IN equivalent, this page delivers verified electrical characteristics, package-specific terminal mapping for the 14-pin PDIP (N) variant, real-world use cases in safety-critical analog front-ends, and validated alternative options for design continuity.
Technical Context
The TLE2064IN uses JFET-input transistors with on-chip Zener trimming for offset voltage stability across temperature. Its architecture supports rail-to-rail output swing under light load (±13.2V at ±15V supply), high common-mode rejection (72–90 dB), and robust supply-voltage rejection (75–93 dB).
It operates over –40°C to +85°C (I-suffix grade), features 2.6 V/µs slew rate at ±15V, 40 kHz maximum output-swing bandwidth, and maintains phase margin ≥46° with 10kΩ//100pF load - enabling stable unity-gain buffer and active filter configurations without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.1 MHz - enables stable closed-loop operation up to ~100 kHz in gain-of-10 configurations. |
| Supply Current per Channel | 120 μA (typical) - allows four-channel operation within 500 μA total, ideal for battery-backed or energy-constrained systems. |
| Input Offset Voltage (max) | 6 mV (over –40°C to +85°C) - supports DC-coupled sensor interfaces requiring <10 mV error budget. |
| Output Drive Capability | Specified into 100Ω loads - delivers ±2.5V min swing at ±5V supply, enabling direct driving of low-impedance ADC inputs or transmission lines. |
| Common-Mode Input Range | –11 V to +13 V at ±15V supply - accommodates bipolar sensor signals without level-shifting circuitry. |
| Input Bias Current | ±10 pA (typical) - preserves high-impedance source integrity in piezoelectric or photodiode front-ends. |
| Supply Voltage Range | ±3.5 V to ±18 V - supports dual-rail operation in legacy industrial systems using ±15V rails. |
Pinout & Package
The TLE2064IN is housed in a 14-pin plastic DIP (PDIP) package (N), measuring 19.3 mm × 9.4 mm, with through-hole mounting and industry-standard footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or next-stage input; capable of ±13.2V swing into 10kΩ at ±15V supply. |
| 2 | IN– A | Inverting input for channel A - high-impedance (6 TΩ || 1 pF) node sensitive to PCB leakage and guarding requirements. |
| 3 | IN+ A | Non-inverting input for channel A - matched bias current path; requires symmetrical trace routing for optimal CMRR. |
| 4 | VCC– | Negative supply rail - must be decoupled locally with 0.1 μF ceramic capacitor to minimize PSRR degradation. |
| 5 | IN+ B | Non-inverting input for channel B - electrically isolated from channel A; shares no internal substrate coupling. |
| 6 | IN– B | Inverting input for channel B - independent high-Z node; layout symmetry with pins 2/3 recommended. |
| 7 | OUT B | Amplifier B output - identical drive strength and thermal performance to pin 1; supports independent feedback networks. |
| 8 | NC | No connect - internally unconnected; must remain floating; not usable as heatsink or ground tie. |
| 9 | OUT C | Amplifier C output - third independent output; same AC/DC specs as channels A/B; enables triple-redundant signal paths. |
| 10 | IN– C | Inverting input for channel C - matches pin 2 electrical behavior; critical for matched multi-channel calibration. |
| 11 | IN+ C | Non-inverting input for channel C - reference point for differential sensing across three simultaneous channels. |
| 12 | VCC+ | Positive supply rail - shared by all four amplifiers; requires low-ESR bulk + local ceramic decoupling. |
| 13 | IN+ D | Non-inverting input for channel D - fourth independent input; enables full-bridge signal conditioning or quad-channel data acquisition. |
| 14 | IN– D | Inverting input for channel D - completes quad-channel set; pin 14 and pin 13 form final differential pair interface. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad FET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE2064CD | Same core silicon, SOIC-14 package (D), rated for 0°C to 70°C (C-suffix); 6 mV VIO max, 120 μA ICC. | Surface-mount assembly only; lacks extended temperature range; lower thermal mass improves transient response. | Select when board space is constrained and ambient operating temperature remains below 70°C. |
| TL074CP | JFET-input quad op-amp; wider GBW (3 MHz), higher supply current (1.4 mA/ch), no guaranteed 100Ω drive spec. | Better bandwidth for AC-coupled audio or communication signals; unsuitable for low-power or high-drive DC applications. | Choose only if higher speed is required and power budget allows >5× increase in quiescent current. |
Compared with TLE2064IN, TLE2064CD offers identical electrical performance in a smaller SOIC package but sacrifices industrial temperature range, while TL074CP trades ultra-low power and guaranteed high-drive capability for higher bandwidth and higher current consumption - making TLE2064IN uniquely suited for extended-temperature, low-power, high-drive analog front-ends.

FAQ
What is the maximum operating temperature range for the TLE2064IN?
The TLE2064IN is rated for operation from –40°C to +85°C (I-suffix grade), validated across its full electrical specification table including input offset voltage, common-mode rejection ratio, and output swing. This makes it suitable for industrial and avionics environments where ambient temperatures exceed commercial-grade limits, unlike the C-suffix variants limited to 0°C–70°C.
Does the TLE2064IN support rail-to-rail input or output operation?
The TLE2064IN does not provide rail-to-rail input or output operation. Its common-mode input range extends to –11 V to +13 V at ±15 V supply, and output swing reaches ±13.2 V into 10 kΩ - approximately 1.8 V from each rail. For true rail-to-rail performance, consider newer TI families such as the OPAx320 series, but note they lack the TLE2064IN's 36 V supply rating and extended temperature qualification.
Can the TLE2064IN drive a 100Ω load reliably across temperature?
Yes - the TLE2064IN is explicitly specified for high-output-drive performance into 100Ω loads, with guaranteed minimum output swing of ±2.5 V at ±5 V supply and ±12 V at ±15 V supply across –40°C to +85°C. This capability is confirmed in Section 5.5 and 5.9 of the datasheet and distinguishes it from earlier low-power BiFET amplifiers.
What is the input bias current specification for the TLE2064IN at 25°C?
The TLE2064IN exhibits an input bias current of ±10 pA (typical) at 25°C, with a maximum of 5 nA over the full –40°C to +85°C range. This ultra-low value stems from its JFET-input architecture and enables accurate amplification of signals from high-impedance sources such as photodiodes, piezoelectric sensors, and pH electrodes without significant DC error.
Is the TLE2064IN pin-compatible with other members of the TLE206x family?
Yes - the TLE2064IN (14-pin PDIP) shares identical pinout with all other TLE2064 variants including TLE2064CD (SOIC-14), TLE2064ID (SOIC-14, I-temp), and TLE2064CN (PDIP, C-temp). Pin functions are fully consistent across packages and temperature grades, allowing drop-in replacement where thermal and mechanical constraints permit.
