Product details
Overview
TLV27L2CDRG4 from Texas Instruments is a dual-channel micropower rail-to-rail output operational amplifier designed for ultra-low-power signal conditioning in battery-operated systems. It delivers 160 kHz gain-bandwidth, 0.1 V/μs slew rate, 7 μA per channel quiescent current, and operates from 2.7 V to 16 V supply across 0°C to 70°C. It serves as a low-power upgrade to TLC27L2 in portable medical sensors and smoke detectors.
For engineers reviewing the TLV27L2CDRG4 datasheet, TLV27L2CDRG4 pinout, TLV27L2CDRG4 application, or TLV27L2CDRG4 equivalent, key selection criteria include its 7 μA/channel supply current, rail-to-rail output swing down to 2.7 V, 5 mV max input offset voltage, −40°C to 125°C industrial-grade variants, and SOIC-8 packaging with standard lead finish.
Technical Context
The TLV27L2CDRG4 employs BiMOS input stage architecture enabling 1 pA typical input bias current and rail-to-rail output swing within 50 mV of each rail at ±5 V supply. Its 160 kHz unity-gain bandwidth and 0.06 V/μs typical slew rate support precision DC-coupled amplification with minimal phase shift up to 10 kHz.
Designed for single-supply operation, it features an input common-mode range extending from −0.2 V to VS+1.2 V and output swing limited only by internal saturation-enabling full dynamic range utilization in 3.3 V or 5 V systems without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports single-cell Li-ion (3.0–4.2 V), two alkaline (3.0 V min), or ±8 V split supplies. |
| Quiescent Current | 7 μA per channel - enables >1-year battery life in 10 μA system sleep modes with active sensing intervals. |
| Gain Bandwidth Product | 160 kHz - sufficient for anti-aliasing filters, sensor front-end amplification, and low-frequency instrumentation. |
| Input Offset Voltage | 5 mV max - ensures ≤0.5% error in 1 V full-scale bridge sensor outputs without trimming. |
| Input Bias Current | 1 pA typical - preserves high-impedance source integrity (e.g., pH electrodes, photodiode transimpedance inputs). |
| Output Swing | Within 50 mV of rails at ±5 V - delivers true 0–5 V output range for ADC interfacing without external level shifters. |
| Operating Temperature | 0°C to 70°C - qualified for commercial-grade embedded control and consumer electronics environments. |
Pinout & Package
TLV27L2CDRG4 is housed in an 8-pin SOIC (D) package with 1.27 mm pitch, 4.9 mm × 3.9 mm body, and standard JEDEC MS-012AC footprint. Thermal resistance θJA = 176°C/W enables 710 mW power dissipation at TA ≤ 25°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 100 mA; rail-to-rail swing supports direct interface to SAR ADC reference buffers. |
| 2 | IN− A | Inverting input A - high-impedance node; requires guard ring routing to minimize leakage-induced offset drift. |
| 3 | IN+ A | Non-inverting input A - accepts signals from −0.2 V to VS+1.2 V; enables level-shifting-free sensor biasing. |
| 4 | GND | Analog ground reference - must connect to low-impedance ground plane; shared with digital ground only at single point. |
| 5 | VDD | Positive supply - decouple with 0.1 μF ceramic + 6.8 μF tantalum placed ≤2 mm from pin. |
| 6 | IN− B | Inverting input B - electrically isolated from Channel A; supports dual-sensor differential measurement. |
| 7 | IN+ B | Non-inverting input B - identical CMVR and bias specs as Channel A; enables matched dual-channel configurations. |
| 8 | OUT B | Amplifier B output - independent output stage; allows simultaneous processing of two analog signals without crosstalk. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full 0 V to VS output range at 100 μA load, eliminating need for external level-shifting circuitry in 3.3 V microcontroller systems. |
| 1 pA input bias current | Preserves signal integrity from high-impedance sources like piezoelectric sensors or electrochemical cells without loading-induced gain error. |
| 7 μA per channel supply current | Enables continuous monitoring in battery-powered devices with multi-year operational lifetime on coin-cell batteries. |
| 160 kHz bandwidth at 7 μA | Provides usable AC response for slow-varying biosignals (ECG, temperature) while maintaining micropower efficiency. |
| −40°C to 125°C industrial variants available | Ensures functional reliability in automotive cabin modules, industrial PLC I/O, and outdoor environmental monitors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2372IDR | Higher 20 μA/channel IQ, 3 MHz GBW, same SOIC-8 package and rail-to-rail output. | Better for higher-speed filtering but consumes ~3× more current; less suitable for decade-long battery life. | Select when bandwidth >1 MHz is required and power budget allows ≥20 μA/channel. |
| TLC2272CDR | 62.5 μA/channel IQ, 2.2 MHz GBW, wider 2.7–16 V supply, lower 1.5 mV VIO. | Superior DC precision and speed, but 9× higher quiescent current limits use in ultra-low-power designs. | Choose when offset voltage <2 mV is critical and system can support >60 μA/channel continuous draw. |
Compared with TLV2372IDR and TLC2272CDR, TLV27L2CDRG4 provides the lowest power envelope (7 μA/channel) for sub-200 kHz signal paths, making it optimal for energy-constrained sensing nodes where battery longevity outweighs bandwidth needs.

FAQ
What is the maximum recommended supply voltage for TLV27L2CDRG4?
The absolute maximum supply voltage for TLV27L2CDRG4 is 16.5 V, but the recommended operating range is 2.7 V to 16 V. Operation above 16 V risks permanent damage; sustained use at 16 V is acceptable only with adequate thermal derating per the dissipation rating table (710 mW at 25°C ambient in SOIC-8).
Does TLV27L2CDRG4 support rail-to-rail input operation?
No, TLV27L2CDRG4 does not support rail-to-rail input. Its input common-mode voltage range is specified from −0.2 V to VS−1.2 V - meaning it cannot accept signals within 1.2 V of the positive rail. However, its rail-to-rail output capability remains fully functional across the entire supply range.
Is TLV27L2CDRG4 pin-compatible with TLC27L2CDR?
Yes, TLV27L2CDRG4 is pin-compatible with TLC27L2CDR in the SOIC-8 (D) package. Both share identical pinout: OUT A, IN− A, IN+ A, GND, VDD, IN− B, IN+ B, OUT B. This allows direct replacement in legacy designs seeking lower quiescent current and improved output swing.
What is the typical input offset voltage drift over temperature for TLV27L2CDRG4?
The typical input offset voltage drift for TLV27L2CDRG4 is 1.1 μV/°C, measured at 25°C under standard test conditions. This low drift ensures minimal calibration drift in temperature-varying environments such as industrial sensor nodes or automotive cabin modules.
Can TLV27L2CDRG4 drive capacitive loads up to 100 pF without instability?
TLV27L2CDRG4 is stable with capacitive loads ≤50 pF when using recommended PCB layout practices. Driving 100 pF loads may induce peaking or oscillation; TI recommends adding a 10–100 Ω series resistor between output and capacitive load to isolate the pole and maintain ≥45° phase margin.
