Product details
Overview
TLV2264IN from Texas Instruments is a quad rail-to-rail output CMOS operational amplifier optimized for low-voltage, low-power applications. It delivers 950 µV max input offset voltage (A-grade), 12 nV/√Hz input voltage noise at 1 kHz, 500 µA max supply current per amplifier, and operates from 2.7 V to 8 V. It is used in precision signal conditioning of high-impedance sources such as piezoelectric transducers in battery-powered remote sensors.
For engineers reviewing the TLV2264IN datasheet, TLV2264IN pinout, TLV2264IN application, or TLV2264IN equivalent, key selection criteria include its rail-to-rail output swing, sub-1 pA input bias current at 25°C, guaranteed operation down to 2.7 V, and A-grade precision specification across −40°C to +125°C.
Technical Context
The TLV2264IN uses Advanced LinCMOS™ process technology to achieve high input impedance (>10¹² Ω), low input bias current (1 pA typ), and rail-to-rail output capability without external charge pumps. Its architecture supports both single-supply (e.g., 3 V or 5 V) and split-supply operation while maintaining full common-mode input range extending to the negative rail.
It features a gain-bandwidth product of 0.67 MHz at 3 V and 0.71 MHz at 5 V, slew rate of 0.35–0.55 V/µs, and phase margin of 55°–56° with 100 pF capacitive load - enabling stable unity-gain buffer and sensor interface configurations without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - enables direct use with single-cell Li-ion (3.0–3.7 V), two-cell alkaline (3.0 V), or 5 V logic rails. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - ensures ≤0.5 mV error in 12-bit ADC front-end with ±2.5 V reference. |
| Supply Current (per amp) | 1 mA max (four amps) at 3 V - supports ultra-low-power operation in always-on sensor nodes. |
| Input Voltage Noise | 12 nV/√Hz at f = 1 kHz - critical for preserving SNR in low-level analog signal chains (e.g., thermopile or strain gauge). |
| Common-Mode Input Range | Includes negative rail (VDD−) - allows direct interfacing with ground-referenced sensors without level-shifting. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs like ADS7822 or MCP3201, maximizing resolution utilization. |
| Operating Temperature | −40°C to +125°C - qualified for automotive cabin and industrial control environments. |
Pinout & Package
TLV2264IN is supplied in a 14-pin plastic DIP (N) package with through-hole mounting and 0.3-inch body width.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - drives loads up to ±50 mA; rail-to-rail swing supports full-scale ADC input. |
| 2 | IN− A | Inverting input - high-impedance node (10¹² Ω) minimizes loading on high-Z sources like pH electrodes. |
| 3 | IN+ A | Non-inverting input - accepts signals down to VDD−, enabling true single-supply instrumentation amplifier topologies. |
| 4 | VDD− / GND | Negative supply / ground reference - shared return for all four amplifiers; must be low-impedance. |
| 5 | IN+ B | Non-inverting input of second amplifier - electrically isolated from other channels; supports dual-sensor readout. |
| 6 | IN− B | Inverting input of second amplifier - matched bias current ensures common-mode rejection in differential pairs. |
| 7 | OUT B | Output of second amplifier - independent channel; no crosstalk specified between channels. |
| 8 | OUT C | Output of third amplifier - pin-compatible with standard quad op-amp layouts (e.g., LM324 footprint). |
| 9 | IN− C | Inverting input of third amplifier - identical electrical specs to pins 2 and 6; supports multi-channel filtering. |
| 10 | IN+ C | Non-inverting input of third amplifier - enables simultaneous monitoring of three independent analog signals. |
| 11 | VDD+ | Positive supply - accepts 2.7–8 V; decoupling capacitor (0.1 µF) required near pin for stability. |
| 12 | IN+ D | Non-inverting input of fourth amplifier - completes quad configuration; supports 4-channel data acquisition. |
| 13 | IN− D | Inverting input of fourth amplifier - matched performance enables consistent gain calibration across all channels. |
| 14 | OUT D | Output of fourth amplifier - fully specified rail-to-rail swing; usable as reference buffer or DAC output driver. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 10 mV of VDD− and VDD+ at light loads - eliminates need for level-shifting before 12-bit SAR ADCs. |
| Low input bias current | 1 pA typical at 25°C - prevents signal degradation in >1 GΩ source impedances (e.g., electret microphones). |
| Low-noise design | 12 nV/√Hz at 1 kHz - preserves signal integrity in low-amplitude sensor interfaces without requiring post-amplification. |
| Wide supply range | 2.7 V to 8 V - supports direct integration into mixed-voltage systems (e.g., 3.3 V MCU + 5 V analog subsystem). |
| Automotive qualification | A-grade (TLV2264AI) variant qualified per AEC-Q100 - TLV2264IN shares same die and process, rated for −40°C to +125°C. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2264AIP | Same die, TSSOP-14 package; 950 µV VIO guaranteed; identical electrical specs. | Surface-mount assembly; smaller footprint; requires reflow profile control. | Select TLV2264AIP for space-constrained PCBs where automated SMT is available. |
| LM324N | Bipolar input; 3 mV VIO max; 1.2 mA per amp; no rail-to-rail output; 0°C to 70°C only. | Legacy cost-sensitive designs; non-critical accuracy; higher power budget acceptable. | Choose LM324N only when precision, low power, or extended temperature are not required. |
Compared with TLV2264IN, TLV2264AIP offers identical performance in a surface-mount package for modern layouts, while LM324N trades precision, power, and temperature range for legacy compatibility and lower unit cost - making TLV2264IN optimal for new designs demanding accuracy and efficiency.

FAQ
What is the maximum supply voltage for TLV2264IN?
The absolute maximum supply voltage for TLV2264IN is 16 V, but the recommended operating range is 2.7 V to 8 V. Operating above 8 V may degrade long-term reliability and is not characterized per datasheet specifications. For robust 5 V or 3.3 V system integration, TLV2264IN delivers full performance within this range.
Does TLV2264IN support true rail-to-rail input?
No, TLV2264IN supports rail-to-rail *output* swing but has a common-mode input voltage range that extends to the negative rail (VDD−) and up to VDD+ −1.3 V. This means it accepts inputs down to ground in single-supply mode but cannot handle signals at the positive rail - unlike some newer op-amps with full rail-to-rail input.
Is TLV2264IN pin-compatible with LM324N?
Yes, TLV2264IN uses the standard 14-pin DIP (N) package with identical pinout to LM324N, enabling drop-in replacement in existing layouts. However, note differences in supply current (1 mA vs. ~1.2–1.5 mA), input offset (950 µV vs. 3 mV), and output swing (rail-to-rail vs. ~1.5 V from rails) - circuit validation is recommended.
What is the input bias current specification for TLV2264IN at 125°C?
At 125°C, TLV2264IN has a maximum input bias current of 800 pA (full temperature range spec). At 25°C, typical value is 1 pA, and maximum is 60 pA. This ultra-low bias enables accurate measurement from high-impedance sources even at elevated temperatures.
Can TLV2264IN drive a 10 kΩ load while maintaining rail-to-rail output?
Yes, TLV2264IN guarantees rail-to-rail output swing into ≥10 kΩ loads at room temperature. With 50 mA short-circuit current capability and 270 Ω closed-loop output impedance at 100 kHz, it maintains linearity and settling performance driving standard ADC input networks and RC filters.
