Product details
Overview
TLV274QDRG4Q1 from Texas Instruments is a quad-channel automotive-grade rail-to-rail output operational amplifier with 3-MHz unity-gain bandwidth, 2.4 V/µs slew rate, and 550 µA per channel supply current. It operates from 2.7 V to 16 V single supply (±1.35 V to ±8 V split), features 1 pA input bias current and 39 nV/√Hz input voltage noise, and is qualified for −40°C to +125°C operation in engine control units and battery management systems.
For engineers reviewing the TLV274QDRG4Q1 datasheet, TLV274QDRG4Q1 pinout, TLV274QDRG4Q1 application, or TLV274QDRG4Q1 equivalent, key selection criteria include rail-to-rail output swing at low supply voltage, CMOS input impedance for high-impedance sensor interfacing, automotive AEC-Q100 qualification, and compatibility with Li-ion powered microcontrollers such as MSP430.
Technical Context
The TLV274QDRG4Q1 implements a CMOS input stage enabling ultra-low input bias current (1 pA typ) and wide common-mode input range (0 V to VDD−1.35 V). Its rail-to-rail output stage delivers >98% of supply rail swing under 1-mA load across the full temperature range.
It achieves 3-MHz unity-gain bandwidth with only 550 µA per channel quiescent current, maintaining phase margin ≥65° into 10-pF capacitive loads. The device is fully specified for both single-supply (2.7–16 V) and split-supply (±1.35–±8 V) operation, with PSRR of 70 dB and CMRR of 80 dB at 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 3 MHz unity-gain bandwidth enables stable amplification of signals up to audio and low-speed data acquisition frequencies. |
| Slew Rate | 2.4 V/µs supports 1-Vpp output at 380 kHz without distortion, suitable for fast-settling sensor buffers. |
| Supply Current | 550 µA per channel allows four op-amps to operate within 2.2 mA total, ideal for power-constrained automotive modules. |
| Input Bias Current | 1 pA typical enables direct connection to high-impedance sources like piezoelectric sensors or pH electrodes without signal loss. |
| Rail-to-Rail Output | Swings within 100 mV of rails at 1 mA load ensures full dynamic range utilization in 3.3-V or 5-V systems. |
| Operating Temp | −40°C to +125°C automotive grade supports placement in under-hood ECUs and transmission control units. |
| Input Noise | 39 nV/√Hz at 1 kHz permits low-noise amplification of millivolt-level thermocouple or strain gauge outputs. |

FAQ
What is the maximum operating supply voltage for TLV274QDRG4Q1?
The absolute maximum supply voltage for TLV274QDRG4Q1 is 16.5 V, but the recommended operating range is 2.7 V to 16 V for single-supply operation. This allows use with 12-V automotive systems and up to ±8 V in split-supply configurations. Exceeding 16.5 V risks permanent damage per the absolute maximum ratings table in the datasheet.
Does TLV274QDRG4Q1 support rail-to-rail input operation?
No, TLV274QDRG4Q1 features rail-to-rail *output* only. Its common-mode input voltage range is specified as 0 V to VDD−1.35 V, meaning the inputs cannot swing to the positive rail. For true rail-to-rail input/output, consider alternatives like the TLV2374-Q1, which is explicitly documented with RRI/O capability.
What is the input offset voltage specification for TLV274QDRG4Q1 over temperature?
TLV274QDRG4Q1 has a maximum input offset voltage of 7 mV across the full −40°C to +125°C automotive temperature range. At 25°C, the typical value is 0.5 mV with a maximum of 5 mV. Offset voltage drift is 2 µV/°C, resulting in predictable, bounded error accumulation over temperature.
Can TLV274QDRG4Q1 drive capacitive loads directly?
TLV274QDRG4Q1 can drive ≤10 pF capacitive loads stably. For larger loads (e.g., ADC input capacitance or long PCB traces), a series resistor (RNULL ≥20 Ω) must be placed between the op-amp output and the load to maintain ≥65° phase margin and prevent oscillation, as confirmed in the "Driving a Capacitive Load" application note.
Is TLV274QDRG4Q1 pin-compatible with standard TLV274 variants?
Yes, TLV274QDRG4Q1 uses the same SOIC-14 (D) package and pinout as non-automotive TLV274 variants, including identical terminal assignments for all 14 pins. However, it is not pin-compatible with TLV274QPWRQ1 (TSSOP-14) due to differing package dimensions and pad layout.
