TLV1851-Q1

The TLV1851-Q1 is a high-precision, low-power operational amplifier manufactured by Texas Instruments, designed for automotive and industrial applications requiring robust performance under harsh conditions. It operates with a supply voltage range from 2.7 V to 5.5 V, making it compatible with both single-supply and dual-supply systems. The device features a wide bandwidth of 10 MHz and a high slew rate of 4.5 V/μs, enabling fast response times and accurate signal processing in dynamic environments. This op-amp offers rail-to-rail input and output capabilities, allowing full utilization of the supply voltage range without signal clipping, which is essential for maximizing dynamic range in sensor interfaces and analog signal conditioning circuits. It provides a low offset voltage of 1 mV (max) and low drift over temperature, ensuring consistent accuracy across varying operating conditions—critical for precision measurement systems such as current sensing, temperature monitoring, and battery management. Designed to meet AEC-Q100 Grade 1 qualification standards, the TLV1851-Q1 is built for reliability in automotive applications, including engine control units, infotainment systems, and ADAS (Advanced Driver Assistance Systems). Its enhanced EMI immunity and integrated protection features, such as short-circuit and thermal shutdown, ensure stable operation even in electrically noisy environments typical of vehicle electronics. The TLV1851-Q1 consumes only 320 μA of quiescent current per channel, making it ideal for power-sensitive designs where efficiency is paramount. Its small package options—including the SC-70 and SOIC—support space-constrained layouts while maintaining excellent thermal performance. The device supports both single-channel and dual-channel configurations in a compact footprint, offering flexibility in system design. In addition to its core amplification function, the TLV1851-Q1 includes features like internal compensation for stability across a wide range of load conditions, minimizing external component requirements. It is suitable for use in filter circuits, transimpedance amplifiers, and buffer applications, particularly where high linearity and low noise are required. The combination of high performance, low power, and automotive-grade reliability makes this op-amp a preferred choice for next-generation embedded systems demanding precision, durability, and energy efficiency.
