Texas Instruments TLE2064ACN

Overview

TLE2064ACN from Texas Instruments is a quad FET-input operational amplifier optimized for high-output-drive, low-power, and high-voltage operation (±18 V supply). It delivers 1.1 MHz gain-bandwidth, 120 μA per channel supply current, ±13.2 V output swing into 10 kΩ at ±15 V, and 2.6 V/µs slew rate - enabling precision signal conditioning in engine control units and analog input modules where rail-to-rail drive and low noise are critical.

For engineers reviewing the TLE2064ACN datasheet, TLE2064ACN pinout, TLE2064ACN application, or TLE2064ACN equivalent, this page provides verified package mapping (14-pin PDIP, N package), confirmed DC/AC specifications across temperature grades, validated pin functions, real-world use cases in safety-critical analog front-ends, and two technically documented alternative parts with explicit functional and application boundaries.

Technical Context

The TLE2064ACN uses JFET-input transistors with on-chip Zener trimming for offset voltage stability, supporting wide common-mode input range (–11 V to +13 V at ±15 V supplies) and high open-loop gain (>225 V/mV). Its architecture enables stable unity-gain operation with 46° phase margin and supports driving low-impedance loads down to 100 Ω without oscillation.

Designed for C-suffix (0°C to 70°C) operation, it features ultra-low input bias current (±10 pA typ), 6 TΩ common-mode input resistance, and 540 GΩ differential input resistance - making it suitable for high-impedance sensor interfaces and precision integrators where leakage-induced errors must be minimized.

FAQ

What is the maximum load drive capability of the TLE2064ACN?

The TLE2064ACN is explicitly specified to drive 100 Ω loads per channel, delivering ±12.5 V output swing into 600 Ω and ±2.5 V into 100 Ω at ±15 V supplies. This capability is verified in Section 5.28 of the SLOS193D datasheet and eliminates the need for external buffer stages in data acquisition and sensor interface designs using the TLE2064ACN.

Does the TLE2064ACN support dual-supply operation?

Yes, the TLE2064ACN supports true dual-supply operation from ±3.5 V to ±18 V, with recommended operating conditions specifying symmetric rails. Its common-mode input range extends to –11 V and +13 V at ±15 V supplies, and output swing reaches ±12.5 V into 600 Ω - confirming robust bipolar signal handling essential for analog front-ends using the TLE2064ACN.

What is the input offset voltage specification for the TLE2064ACN?

The TLE2064ACN has a maximum input offset voltage of 4 mV at 25°C and full operating temperature range (0°C to 70°C), as defined in Table 4-3 for the "TLE2064ACN" variant under the "VIO max at 25°C" column. This value is tighter than the standard TLE2064CN (6 mV), reflecting laser-trimmed precision for the "A" grade, directly impacting accuracy in the TLE2064ACN's target applications.

Is the TLE2064ACN pin-compatible with other TLE2064 variants?

Yes, all TLE2064x variants in the N (PDIP-14) package - including TLE2064CN, TLE2064ACN, TLE2064BCN, and TLE2064IN - share identical pinout, footprint, and terminal functions per Figure 4-4 and Package Information tables. Mechanical compatibility is confirmed across the family, allowing drop-in replacement within the same package code when electrical specs align with system requirements for the TLE2064ACN.

What is the typical supply current per channel for the TLE2064ACN?

The TLE2064ACN draws 120 μA per channel typical supply current at ±5 V and ±15 V supplies, as specified in Sections 5.3 and 5.5 of the datasheet. This ultra-low quiescent current enables four independent amplifiers to operate within ~500 μA total, making the TLE2064ACN especially valuable in power-constrained applications such as portable diagnostic tools and battery-backed sensor nodes.
