Texas Instruments TLC2252CPWR

Overview

TLC2252CPWR from Texas Instruments is a dual rail-to-rail output operational amplifier in an 8-pin TSSOP package, delivering 19 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and 35 µA per channel supply current. It operates from ±2.2 V to ±8 V supplies, supports common-mode input down to the negative rail, and targets low-power signal conditioning in battery-powered sensor interfaces and ADC drivers.

For engineers reviewing the TLC2252CPWR datasheet, TLC2252CPWR pinout, TLC2252CPWR application, or TLC2252CPWR equivalent, key selection criteria include its micropower consumption, rail-to-rail output swing, low-input-bias-current performance for high-impedance sources, and compatibility with single- or split-supply 5 V / ±5 V systems.

Technical Context

The TLC2252CPWR uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining CMOS-level input impedance (10¹² Ω differential and common-mode resistance) and ultra-low input bias current (1 pA typ). Its architecture enables operation with input voltages extending to the negative supply rail, supporting true single-supply sensor front-ends.

It delivers 70–83 dB common-mode rejection and 80–95 dB supply-voltage rejection across 0°C to 70°C, with a 0.2 MHz gain-bandwidth product and 63° phase margin at unity gain into 50 kΩ || 100 pF, ensuring stable operation in precision DC-coupled and low-frequency AC applications.

FAQ

What is the maximum operating supply voltage for the TLC2252CPWR?

The TLC2252CPWR supports a total supply voltage range of ±2.2 V to ±8 V in split-supply mode, or 4.4 V to 16 V in single-supply configurations. Absolute maximum ratings specify VDD+ ≤ 8 V and VDD– ≥ –8 V. Exceeding these limits risks permanent damage. Operation at ±5 V or 5 V single supply is fully characterized and recommended for most designs using the TLC2252CPWR.

Does the TLC2252CPWR support rail-to-rail input voltage range?

No, the TLC2252CPWR does not provide rail-to-rail input common-mode range. Its common-mode input voltage extends to the negative rail (VDD–) but only up to VDD+ – 1.5 V under recommended conditions. For example, at 5 V supply, the valid input range is 0 V to 3.5 V. This limitation is documented in the "Recommended Operating Conditions" table of the TLC2252CPWR datasheet and applies across all temperature ranges.

Can the TLC2252CPWR drive capacitive loads directly?

The TLC2252CPWR is stable with capacitive loads up to 100 pF when configured with RL = 50 kΩ, as verified by 63° phase margin at unity gain. Driving larger capacitive loads (e.g., >500 pF) may cause peaking or oscillation. For such cases, an isolation resistor (≥100 Ω) between the TLC2252CPWR output and the load capacitance is required to maintain stability. This behavior is consistent across all operating conditions for the TLC2252CPWR.

What is the input offset voltage specification for the TLC2252CPWR?

The TLC2252CPWR (C-suffix, commercial temperature grade) has a maximum input offset voltage of 1500 µV at TA = 25°C and 1750 µV across the full 0°C to 70°C operating range. Typical value is 200 µV. This parameter is measured under standard test conditions (VDD = 5 V, RL = 100 kΩ) and is distinct from the tighter 850 µV max offered by the TLC2252AIPW variant (A-suffix, improved accuracy grade).

Is the TLC2252CPWR pin-compatible with the TLC2252CP or TLC2252CD?

Yes, the TLC2252CPWR shares identical pinout and electrical functionality with the TLC2252CP (plastic DIP) and TLC2252CD (SOIC), as confirmed by the "TLC2252C, TLC2252AC… D, P, OR PW PACKAGE (TOP VIEW)" diagram in the official datasheet. All three packages implement the same 8-pin dual op-amp topology with matching pin assignments for inputs, outputs, and supplies - enabling drop-in replacement across form factors without PCB redesign.
