Product details
Overview
TLC27M4CDR from Texas Instruments is a LinCMOS™ precision quad operational amplifier optimized for low-power, rail-to-rail output (negative rail inclusive), high-input-impedance analog signal conditioning in 0°C to 70°C industrial environments. It delivers ±300 µV max input offset voltage at 25°C, ±0.6 µV/°C drift, 32 nV/√Hz input noise at 1 kHz, 1.1 MHz unity-gain bandwidth, and 120 µA typical supply current per two amplifiers at 5 V - enabling high-accuracy sensor interfacing and multiplexed data acquisition.
For engineers reviewing the TLC27M4CDR datasheet, TLC27M4CDR pinout, TLC27M4CDR application, or TLC27M4CDR equivalent, this device is selected for precision DC-coupled amplification where low quiescent current, wide common-mode range (–0.2 V to 3.5 V at 5 V), and latch-up immunity are critical - especially in programmable logic controller I/O modules and test equipment front-ends.
Technical Context
The TLC27M4CDR implements a CMOS input stage with 6 TΩ typical input impedance and ESD protection, enabling direct connection to high-impedance sources without loading. Its trimmed offset voltage and low temperature coefficient support stable DC gain over temperature without external trimming.
It operates from 3 V to 16 V single supply across 0°C to 70°C, supports rail-inclusive output swing (VOL ≤ 50 mV at 5 V), and maintains ≥65 dB CMRR and ≥70 dB PSRR - making it suitable for mixed-signal systems where supply rejection and common-mode rejection must coexist with low power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input offset voltage | ±300 µV max at 25°C, 5 V supply - enables <1 LSB error in 12-bit ADC front-ends without calibration |
| Offset voltage drift | ±0.6 µV/°C - ensures <2.4 µV total drift over 0°C–70°C operating range |
| Input noise density | 32 nV/√Hz at 1 kHz - supports low-noise amplification of microvolt-level sensor signals |
| Unity-gain bandwidth | 1.1 MHz - sufficient for anti-aliasing filtering and closed-loop gain up to ~100× at DC–10 kHz |
| Supply current (per two amps) | 120 µA typical at 25°C, 5 V - allows four-channel operation under 500 µA total, ideal for battery-backed systems |
| Common-mode input range | –0.2 V to 3.5 V at 5 V supply - accepts inputs below ground and up to 0.5 V below VDD |
| Output voltage swing | VOL ≤ 50 mV, VOH ≥ 3.2 V at 5 V - delivers true rail-to-negative-rail output with >3 Vpp swing into 10 kΩ |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV274IDR | Lower offset (250 µV max), lower noise (29 nV/√Hz), but narrower supply range (2.7–16 V) and no C-temp grade | Optimized for 2.7 V battery-powered systems; lacks extended temp validation for industrial ambient | Select TLV274IDR only if operating below 3 V or requiring sub-300 µV offset at cost of reduced temp margin |
| OPA2277UA/2K5 | Higher precision (10 µV max offset), bipolar input (2 nA bias), higher supply current (800 µA), SOIC-8 dual | Requires two devices for quad function; better DC accuracy but 6× higher power and no rail-to-rail output | Choose OPA2277UA/2K5 only when ultra-low offset dominates over power and output swing requirements |
Compared with TLV274IDR, TLC27M4CDR offers validated 0°C–70°C operation and wider 3 V minimum supply; versus OPA2277UA/2K5, it delivers quad integration, rail-to-rail output, and 1/6th the supply current - prioritizing space, power, and single-supply flexibility over ultimate DC precision.

FAQ
What is the maximum operating temperature range for the TLC27M4CDR?
The TLC27M4CDR is rated for operation from 0°C to 70°C (C-suffix grade). This range is validated per TI's SLOS093E datasheet Section 6.3 and Table 4-1, and applies to all electrical characteristics including offset voltage, CMRR, and supply current. Operation outside this range may result in unguaranteed performance or reliability degradation.
Does the TLC27M4CDR support rail-to-rail output swing?
Yes, the TLC27M4CDR provides rail-to-rail output swing relative to the negative rail (GND), with low-level output voltage (VOL) ≤ 50 mV at 25°C and 5 V supply (Section 6.4). However, it does not swing fully to the positive rail - VOH ≥ 3.2 V at 5 V, leaving ~1.8 V headroom. This "rail-to-negative-rail" behavior is confirmed in both 5 V and 10 V test conditions.
What is the input bias current specification for the TLC27M4CDR?
The TLC27M4CDR exhibits typical input bias current of ±10 pA at 25°C and ±60 pA maximum across 0°C to 70°C (Section 6.4). This ultra-low bias enables use with high-impedance sources such as piezoelectric sensors or photodiode transimpedance nodes without significant DC error or stability compromise.
Can the TLC27M4CDR be used with a single 3 V supply?
Yes - the TLC27M4CDR supports single-supply operation down to 3 V across its rated 0°C to 70°C range (Section 6.3). At 3 V, common-mode input range is –0.2 V to 2.5 V and output swing remains functional (VOL ≤ 50 mV, VOH ≥ 1.2 V), though bandwidth and slew rate decrease versus 5 V operation per Figure 6-17 and 6-20.
Is the TLC27M4CDR pin-compatible with other TLC27Mxx variants?
Yes - the TLC27M4CDR shares identical SOIC-14 (D) pinout and footprint with all TLC27M4x and TLC27M9x variants (TLC27M4ACDR, TLC27M4BCDR, TLC27M9CDR, etc.), as confirmed in Table 5-1 and Figure 5-1 of the datasheet. Electrical differences (offset grade, temp range) do not affect physical compatibility.
