Product details
Overview
TLC2264CPW from Texas Instruments is a quad rail-to-rail output operational amplifier in TSSOP-14 package, designed for precision signal conditioning in single- or split-supply systems. It delivers 12 nV/√Hz input noise at 1 kHz, 1 pA typical input bias current, 500 µA max supply current per amplifier (2 mA total), and rail-to-rail output swing - enabling full dynamic range interfacing with 10-bit to 12-bit ADCs in battery-powered sensor front-ends.
For engineers reviewing the TLC2264CPW datasheet, TLC2264CPW pinout, TLC2264CPW application, or TLC2264CPW equivalent, this page provides verified specifications, validated pin functions, real-world use cases in high-impedance transducer interfaces and portable instrumentation, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The TLC2264CPW implements Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining low input bias current (1 pA typ) and low noise (12 nV/√Hz at 1 kHz). Its common-mode input voltage range extends to the negative rail, supporting true single-supply operation down to 4.4 V.
It is fully specified across 0°C to 70°C (C-suffix), supports ±2.2 V to ±8 V dual supplies or 4.4 V to 16 V single supply, and features 0.71 MHz gain-bandwidth product with 0.55 V/µs slew rate - balancing micropower efficiency and adequate AC performance for DC-coupled sensor amplification and anti-aliasing filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 1 mA max (four amplifiers, VDD = 5 V) - enables multi-channel analog front-ends in space-constrained, battery-operated devices. |
| Input Bias Current | 1 pA typ - preserves signal integrity when amplifying from ultra-high-impedance sources like piezoelectric sensors or pH electrodes. |
| Input Noise Voltage | 12 nV/√Hz at 1 kHz - reduces contribution to system noise floor in precision measurement paths below 100 kHz. |
| Output Swing | Rail-to-rail - delivers full 0–5 V output range with 5 V single supply, maximizing ADC utilization without level-shifting circuitry. |
| Common-Mode Input Range | Includes negative rail (VDD–/GND) - allows direct sensing of signals referenced to ground in single-supply configurations. |
| Gain-Bandwidth Product | 0.71 MHz - supports stable unity-gain buffering and low-pass filtering up to ~100 kHz for sensor signal conditioning. |
| Input Offset Voltage | 2.5 mV max (TLC2264C grade) - suitable for applications where offset can be calibrated out or is secondary to noise and power constraints. |
Pinout & Package
TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed pad not electrically connected, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 12 | Inverting Input (−) | High-impedance differential input for each of four op-amps; accepts signals down to VDD–/GND. |
| 2, 4, 6, 13 | Non-inverting Input (+) | High-impedance differential input; common-mode range includes negative rail for true single-supply operation. |
| 7, 8, 9, 10 | Output | Rail-to-rail output stage drives loads up to ±50 mA; supports 2 VPP swing into 50 kΩ at 185 kHz bandwidth. |
| 14 | VDD+ | Positive supply terminal; operates from 4.4 V to 16 V (single) or ±2.2 V to ±8 V (dual). |
| 11 | VDD–/GND | Negative supply or ground reference; common-mode input and output swing extend to this rail. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers full 0–VDD output swing, eliminating need for level-shifting when driving SAR or sigma-delta ADCs. |
| Low input bias current | 1 pA typical enables accurate amplification of nanoamp-level currents from photodiodes or ion-selective electrodes. |
| Low noise performance | 12 nV/√Hz at 1 kHz improves SNR in low-frequency sensor interfaces where thermal noise dominates. |
| Single- and split-supply operation | Fully characterized at 5 V and ±5 V - simplifies design reuse across portable (single) and industrial (dual) platforms. |
| MicroPower consumption | 1 mA total quiescent current allows integration of four independent channels in <5 mA system analog sections. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2444IPW | Higher supply current (1.25 mA typ), higher GBW (1.8 MHz), lower input offset (1.6 mV max), same TSSOP-14 package. | Better AC performance but 25% higher power; less suitable for sub-5 mA system budgets. | Select TLV2444IPW when settling time or bandwidth >100 kHz is required; retain TLC2264CPW for lowest power in DC/low-freq sensor chains. |
| LMV324IPW | Lower cost, higher input bias current (100 nA), no rail-to-rail input, 1.25 MHz GBW, same TSSOP-14. | Cannot interface directly with ground-referenced sensors; requires input biasing network. | Choose LMV324IPW only in non-critical, cost-sensitive applications where rail-to-rail input is unnecessary and offset calibration is feasible. |
Compared with TLV2444IPW and LMV324IPW, the TLC2264CPW uniquely balances ultra-low input bias current (1 pA), rail-to-rail output, and sub-1 mA total supply current - making it the optimal choice for high-impedance, battery-constrained signal conditioning where precision and power coexist.

FAQ
What is the maximum supply voltage for TLC2264CPW?
The TLC2264CPW supports a maximum supply voltage of 16 V for single-supply operation or ±8 V for split-supply operation. Absolute maximum ratings specify VDD+ ≤ 8 V and VDD– ≥ –8 V relative to midpoint; exceeding these limits risks permanent damage. Operation within recommended ranges (±2.2 V to ±8 V or 4.4 V to 16 V) ensures guaranteed performance and reliability across the 0°C to 70°C temperature range.
Does TLC2264CPW have rail-to-rail input capability?
No, the TLC2264CPW does not feature rail-to-rail input. Its common-mode input voltage range extends to the negative rail (VDD–/GND) but stops 1.5 V below the positive rail (VDD+ – 1.5 V) under recommended operating conditions. This allows true single-supply use with ground-referenced inputs but requires attention to input signal headroom when near VDD+ - unlike rail-to-rail input op-amps such as the TLV2434.
Can TLC2264CPW drive capacitive loads directly?
The TLC2264CPW is stable with capacitive loads up to 100 pF when using a 50 kΩ load resistor, as verified by phase margin (56°) and gain margin (11 dB) measurements in the datasheet. Driving larger capacitive loads (e.g., ADC input capacitance >100 pF) requires isolation resistance or external compensation to prevent peaking or oscillation - a design consideration explicitly called out in the stability section of the SLOS177D datasheet.
What is the input offset voltage specification for TLC2264CPW?
The TLC2264CPW (C-grade) has a maximum input offset voltage of 2.5 mV at 25°C and 3 mV across the full 0°C to 70°C operating range. This value is distinct from the tighter 950 µV max offered by the TLC2264AIPW variant (A-grade). The 2.5 mV spec reflects its positioning as a balanced-performance part - sufficient for many sensor applications where system-level calibration or ratiometric measurement mitigates offset impact.
Is TLC2264CPW pin-compatible with other TSSOP-14 quad op-amps?
The TLC2264CPW uses a standard TSSOP-14 pinout for quad op-amps (pin 1 = A−, pin 2 = A+, pin 3 = B−, etc.), matching industry conventions used by TI's TLV2444, LMV324, and OPA4340. However, electrical characteristics - especially input bias current, noise, and supply current - differ significantly; thus, direct substitution requires validation of gain stability, offset budget, and power constraints in the target application.
