Product details
Overview
TLV2464CN from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-power portable and industrial signal conditioning. It delivers 6.4 MHz gain-bandwidth, 1.6 V/µs slew rate, ±80 mA output drive, 500 µA/channel supply current, and 100 µV input offset voltage - enabling high-fidelity buffering of ADC inputs in battery-powered sensor front-ends.
For engineers reviewing the TLV2464CN datasheet, TLV2464CN pinout, TLV2464CN application, or TLV2464CN equivalent, this device is selected for precision analog acquisition where rail-to-rail swing, low quiescent current, and robust output drive across −40°C to 70°C must coexist without compromising AC performance or DC accuracy.
Technical Context
The TLV2464CN operates from single supplies (2.7–6 V) or split supplies (±1.35–±3 V), with common-mode input range extending beyond rails and rail-to-rail output swing delivering full dynamic range in low-voltage systems. Its architecture supports stable unity-gain operation with 160 pF capacitive load and maintains phase margin ≥44° at 25°C.
Each of its four amplifiers features independent shutdown control (SHDN pins shared per pair), reducing supply current to 0.3 µA/channel in shutdown while placing outputs in high-impedance state. Input noise is specified at 11 nV/√Hz (1 kHz), and CMRR reaches 85 dB at 25°C with VDD = 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable closed-loop operation up to ~1 MHz with moderate gain in sensor signal chains. |
| Slew Rate | 1.6 V/µs - supports clean 10-bit+ ADC sampling of signals up to ~100 kHz without slewing distortion. |
| Supply Current / Channel | 500 µA - allows four-channel precision amplification within 2 mA total, critical for extended battery life. |
| Input Offset Voltage | 100 µV (typ) - ensures <0.002% gain error in 5 V full-scale instrumentation applications. |
| Output Drive | ±80 mA - drives 60 Ω loads directly or interfaces with SAR ADC reference buffers without external boost. |
| Rail-to-Rail I/O | Full input range (0 to VDD) and output swing (within 100 mV of rails) - maximizes SNR in 3.3 V systems. |
| Shutdown Current | 0.3 µA/channel - reduces system standby power by >99.9% when unused channels are disabled. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Same electrical specs but in 14-pin SOIC (PW) package; rated for −40°C to +125°C industrial temp range. | Preferred for surface-mount production and extended-temperature environments like motor drives or outdoor IoT gateways. | Select TLV2464IDR when board space is constrained and operating temperature exceeds 70°C. |
| OPA4340UA | Lower input offset (125 µV max vs. 2000 µV max for TLV2464CN); higher supply current (750 µA/ch); no shutdown function. | Better DC accuracy for precision weigh scales or calibration equipment; unsuitable for battery-critical designs. | Choose OPA4340UA only when sub-200 µV offset is mandatory and shutdown is unnecessary. |
Compared with TLV2464CN, TLV2464IDR offers identical performance in a smaller SOIC package with wider temperature rating, while OPA4340UA trades power efficiency and shutdown capability for tighter DC specifications - making TLV2464CN optimal for cost-sensitive, battery-aware industrial signal chains requiring four matched channels.

FAQ
What is the maximum operating supply voltage for TLV2464CN?
The absolute maximum supply voltage for TLV2464CN is 6 V. Operation above this risks permanent damage. The recommended operating range is 2.7 V to 6 V for single-supply use, or ±1.35 V to ±3 V for split-supply configurations. At 5 V, TLV2464CN delivers ±80 mA output drive and 6.4 MHz bandwidth while maintaining rail-to-rail swing - confirming its suitability for 3.3 V and 5 V industrial systems.
Does TLV2464CN support true rail-to-rail input and output?
Yes, TLV2464CN supports rail-to-rail input (common-mode range extends from GND to VDD) and rail-to-rail output (swing within 100 mV of both rails under 10 mA load). This is confirmed in the datasheet's "Common-mode input voltage range" specification (0 to VDD) and "High-/Low-level output voltage" tests showing VOH ≥ 4.8 V and VOL ≤ 0.2 V at VDD = 5 V - enabling full dynamic range utilization in low-voltage ADC interfaces.
How does the shutdown feature work on TLV2464CN?
TLV2464CN integrates two independent shutdown controls: pins 1/2SHDN (shared by Amps A & B) and 3/4SHDN (shared by Amps C & D). Driving either SHDN pin below 0.7 V places its paired amplifiers into ultralow-current shutdown (0.3 µA/channel), with outputs entering high-impedance state. This is verified in the Electrical Characteristics table under IDD(SHDN), allowing selective channel disablement to reduce system power without affecting active signal paths.
What is the input offset voltage specification for TLV2464CN?
The input offset voltage for TLV2464CN is specified as 2000 µV maximum at 25°C (C-suffix grade), with typical value of 100 µV. Over the full operating temperature range (0°C to 70°C), max VIO rises to 2200 µV. This is documented in the "Electrical Characteristics at VDD = 3 V" table. The low typical offset enables high-accuracy DC-coupled amplification in sensor front-ends where gain errors must remain below 0.05% at 5 V full scale.
Is TLV2464CN suitable for driving ADC inputs directly?
Yes, TLV2464CN is explicitly designed for ADC driving applications. Its rail-to-rail output swing, ±80 mA drive strength, 6.4 MHz GBW, and 1.6 V/µs slew rate ensure clean settling into typical SAR and sigma-delta ADC input capacitances. The datasheet states: "This rail-to-rail dynamic range and high output drive make the TLV246x ideal for buffering analog-to-digital converters." Measured settling time is 1.77 µs to 0.01% with CL = 56 pF, confirming compatibility with 1 MSPS+ ADCs.
