Product details
Overview
TLC25L2ACP from Texas Instruments is a LinCMOS™ dual operational amplifier optimized for ultra-low-power, single-supply operation in battery-powered and energy-constrained systems. It features 5-mV maximum input offset voltage (A-suffix), 20–34 µA supply current at 5 V, rail-to-rail common-mode input range including the negative rail, and stable unity-gain operation - enabling precision signal conditioning in portable medical sensors and remote environmental monitors.
For engineers reviewing the TLC25L2ACP datasheet, TLC25L2ACP pinout, TLC25L2ACP application, or TLC25L2ACP equivalent, key selection criteria include its 1.4–16 V wide supply range, sub-100 nV/√Hz input noise at high source impedance, low 1 pA typical input bias current, and compatibility with high-impedance transducer interfaces requiring minimal offset drift over temperature.
Technical Context
The TLC25L2ACP implements a silicon-gate LinCMOS™ process to achieve extremely high input impedance (>1012 Ω) and ultra-low input bias/offset currents - enabling accurate amplification of signals from megohm-level sources like pH electrodes and piezoresistive strain gauges. Its input stage operates down to the negative rail (GND), supporting true single-supply configurations without level-shifting circuitry.
Designed for stability at unity gain with capacitive loads up to 20 pF, the device delivers predictable phase margin (34° typ at 5 V) and controlled slew rate (0.03 V/µs typ), making it suitable for DC-coupled sensor front-ends and low-frequency active filters where settling time and DC accuracy are prioritized over speed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 16 V - enables direct operation from single alkaline, lithium coin cell, or solar-harvesting power rails without regulation. |
| Input Offset Voltage (Max) | 5 mV at 25°C - A-suffix grade ensures tighter DC error budget for precision instrumentation amplifiers and offset-sensitive analog calculations. |
| Supply Current (Two Amps) | 20–34 µA at 5 V, 25°C - ultra-low quiescent power supports multi-year battery life in always-on IoT endpoints. |
| Input Bias Current (Typ) | 0.6 pA at 25°C - preserves signal integrity when interfacing with high-Z sources such as photodiodes and ceramic microphones. |
| Common-Mode Input Range | Includes GND (VDD–/GND) - eliminates need for negative supply or input biasing networks in single-supply sensor signal chains. |
| Unity-Gain Bandwidth | 85 kHz at 5 V, 25°C - sufficient for DC–10 kHz sensor bandwidths while maintaining stability with minimal external compensation. |
| Input Noise Voltage | 68 nV/√Hz at 1 kHz, RS = 20 Ω - low-noise performance optimized for medium-to-high source impedances in biopotential sensing. |
Pinout & Package
Package: 8-pin Plastic DIP (P), through-hole mounting, industry-standard footprint compatible with manual soldering and wave processes.
| Pin/Terminal | Circuit Role | Design Meaning |

| 2 | Inverting Input of Amplifier 1 (1IN–) | Differential input node with >1012 Ω impedance; requires matched trace routing to minimize offset drift. |
| 3 | Non-Inverting Input of Amplifier 1 (1IN+) | High-impedance reference input; used for sensor excitation feedback or ground-referenced signal acquisition. |
| 4 | Negative Supply / Ground (VDD–/GND) | Reference return path for both amplifiers; must be low-impedance and decoupled locally to suppress supply noise. |
| 5 | Positive Supply (VDD) | Single positive rail input (1.4–16 V); accepts unregulated battery or energy-harvested sources directly. |
| 6 | Output of Amplifier 2 (2OUT) | Independent second output channel; enables dual-stage filtering or differential drive without external ICs. |
| 7 | Inverting Input of Amplifier 2 (2IN–) | Second high-Z differential input; supports independent sensor channel or feedback loop implementation. |
| 8 | Non-Inverting Input of Amplifier 2 (2IN+) | Second reference input; allows simultaneous monitoring of two transducers or ratiometric measurement setups. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462CP | Higher supply current (550 µA), rail-to-rail output (not input), 2.5-mV VIO max | Better for higher-speed, higher-drive applications; unsuitable for sub-50 µA power budgets or GND-referenced inputs | Select TLV2462CP only if output swing to VDD is required and power consumption is secondary to bandwidth. |
| LPV521MG/NOPB | Lower supply current (320 nA), single-channel, 1.25-mV VIO max, but no dual configuration | Requires two devices for dual functionality; superior for nanoamp-level systems but increases layout complexity | Choose LPV521MG/NOPB when ultra-low power dominates and dual-channel integration is not mandatory. |
Compared with TLV2462CP and LPV521MG/NOPB, the TLC25L2ACP uniquely balances ultra-low power (20 µA), dual-channel integration, GND-referenced input, and 5-mV VIO in a legacy-compatible DIP package - making it optimal for cost-sensitive, space-constrained, battery-operated instrumentation where moderate bandwidth suffices.

FAQ
What is the maximum input offset voltage specification for the TLC25L2ACP?
The TLC25L2ACP has a maximum input offset voltage of 5 mV at 25°C, as defined by its "A" suffix grade. This value is guaranteed across the full 0°C to 70°C operating temperature range, with a typical average temperature coefficient of 1.1 µV/°C - ensuring predictable DC error behavior in thermally variable environments.
Can the TLC25L2ACP operate from a 1.5-V alkaline battery without regulation?
Yes, the TLC25L2ACP supports supply voltages as low as 1.4 V, making it fully compatible with a single 1.5-V alkaline cell across its entire discharge curve. At 1.4 V, it maintains functional operation with reduced output swing and bandwidth, while consuming only ~15 µA - ideal for maintenance-free, long-life sensor nodes.
Does the TLC25L2ACP support rail-to-rail input operation?
The TLC25L2ACP supports common-mode input voltage down to the negative rail (GND), but not up to VDD. Its input range is specified as –0.2 V to (VDD – 1 V) at 5 V supply - meaning it is rail-to-rail *at the low end* only. This enables true single-supply use with grounded sensors while retaining adequate headroom for internal circuitry.
What is the typical input bias current of the TLC25L2ACP and why does it matter?
The TLC25L2ACP exhibits a typical input bias current of 0.6 pA at 25°C. This ultra-low value prevents loading of high-impedance sources such as pH electrodes, photodiodes, or capacitive humidity sensors - preserving signal fidelity and eliminating offset errors caused by bias current flowing through source resistance.
Is the TLC25L2ACP pin-compatible with other devices in the TLC25x2 family?
Yes, the TLC25L2ACP shares identical 8-pin DIP pinout and electrical interface with all members of the TLC25x2 family (e.g., TLC252CP, TLC25M2CP). This allows drop-in substitution between low-power (L), medium-power (M), and standard (no suffix) variants - provided supply current, bandwidth, and offset requirements align with the target application.
