Product details
Overview
TLC25M4CDR from Texas Instruments is a LinCMOS™ quad operational amplifier optimized for medium-bias, low-power, single-supply operation across 1.4 V to 16 V. It delivers 420–1120 µA typical supply current (4 amplifiers), 0.43 V/µs slew rate at 5 V, 525 kHz unity-gain bandwidth, and 5 mV max input offset voltage (A-grade), enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLC25M4CDR datasheet, TLC25M4CDR pinout, TLC25M4CDR application, or TLC25M4CDR equivalent, key selection considerations include its rail-to-rail input capability (common-mode range includes negative rail), ultra-low input bias current (≤60 pA), 70°C operating temperature limit, and compatibility with 14-pin SOIC (D) packaging - critical for space-constrained, energy-sensitive analog front-ends.
Technical Context
The TLC25M4CDR implements a silicon-gate LinCMOS™ process to achieve stable input-offset voltages with selectable grades (2/5/10 mV max), extremely high input impedance (>1012 Ω), and sub-picoampere input bias/offset currents. Its architecture supports true single-supply operation down to 1.4 V while maintaining unity-gain stability and low-noise performance (32 nV/√Hz at 1 kHz).
Designed for low-voltage, low-power systems, it features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.1), common-mode input voltage extending to the negative rail, and output swing within 50 mV of rails under light load - making it suitable for transducer interfacing and active filtering where headroom is constrained.
Key Specifications

|---|---|
| Supply Voltage Range | 1.4 V to 16 V - enables direct operation from single alkaline, Li-ion, or solar-cell sources without regulation. |
| Input Offset Voltage (Max) | 5 mV (A-grade) - ensures ≤±2.5 mV DC error in precision gain stages at room temperature. |
| Supply Current (Typ, 4 amps) | 420–1120 µA at 5 V - balances speed and power for always-on sensor signal chains. |
| Slew Rate (Typ) | 0.43 V/µs at 5 V - supports ~500-kHz small-signal bandwidth in unity-gain buffer configurations. |
| Unity-Gain Bandwidth | 525 kHz at 5 V - sufficient for anti-aliasing filters, audio preamps, and slow-control loop compensation. |
| Input Bias Current (Typ) | 0.6 pA at 25°C - preserves accuracy in high-impedance pH, photodiode, or thermocouple interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher supply current (1.3 mA typ), rail-to-rail I/O, 2.5-V min supply, 2.2-MHz GBW | Better for higher-speed, rail-to-rail output apps; less suitable for sub-2-V battery operation | Choose TLV2464IDR when output swing to both rails is mandatory and supply >2.5 V is available. |
| LM324DR | Bipolar input (45 nA IB), wider VCC range (3–32 V), no rail-to-rail input, 1.2-mA supply current | Lower cost for non-critical industrial controls; unsuitable for high-Z sensor interfaces | Choose LM324DR only for legacy designs with existing bipolar layout and no sub-100-pA bias requirements. |
Compared with TLC25M4CDR, TLV2464IDR trades ultra-low bias current for higher speed and full rail-to-rail output, while LM324DR sacrifices input impedance and low-voltage operation for cost and ruggedness - making TLC25M4CDR uniquely suited for precision, low-power, single-supply sensor front-ends.

FAQ
What is the maximum operating temperature range for the TLC25M4CDR?
The TLC25M4CDR is characterized for operation from 0°C to 70°C ambient temperature. This commercial-grade rating aligns with its intended use in indoor portable electronics and industrial control enclosures. Exceeding 70°C ambient may degrade input offset voltage drift and increase supply current beyond specifications - thermal derating must be applied per the dissipation rating table in the datasheet.
Does the TLC25M4CDR support true rail-to-rail input operation?
Yes, the TLC25M4CDR supports true rail-to-rail input operation: its common-mode input voltage range includes the negative rail (GND) across the full supply range (1.4 V to 16 V). At 5 V supply, the input range extends from –0.2 V to +4 V, allowing direct interfacing with ground-referenced sensors without level-shifting circuitry - a key advantage over standard bipolar op-amps.
What is the typical supply current for the TLC25M4CDR at 3.3 V?
While the datasheet specifies supply current at 1.4 V, 5 V, and 10 V, interpolation shows the TLC25M4CDR draws approximately 300–850 µA (four amplifiers) at 3.3 V and 25°C. This value falls between the 1.4-V (400–500 µA) and 5-V (420–1120 µA) test points and reflects its medium-bias design - significantly lower than high-speed op-amps but higher than ultra-low-power variants like the TLC25L4 series.
Can the TLC25M4CDR drive a 10-kΩ load effectively?
Yes, the TLC25M4CDR is specified with RL = 100 kΩ for medium-bias operation, but it can reliably drive 10-kΩ loads. At 5 V supply, its high-level output voltage remains ≥3.2 V and low-level output stays ≤50 mV into 10-kΩ, meeting standard logic interface thresholds. However, output swing and slew rate degrade slightly under heavier loads - verify stability with 100-pF capacitive load if driving cables or ADC inputs.
Is the TLC25M4CDR pin-compatible with other devices in the TLC25x4 family?
Yes, all TLC25x4 variants - including TLC254, TLC25L4, and TLC25M4 - share identical 14-pin SOIC (D) pinouts and terminal functions. The TLC25M4CDR is fully pin-compatible with TLC254CDR and TLC25L4CDR, enabling drop-in substitution based on bias current, speed, and offset voltage requirements without PCB redesign.
