OPA4134UAG4

The OPA4134UAG4 is a low power, rail-to-rail, single high-voltage amplifier that is designed for high-speed and low-noise audio applications. It can drive single-supply signals from supply voltages as low as +2 V and as high as +18 V. This amplifier features low supply current, wide bandwidth, good common-mode rejection ratio, and good temperature performance, making it ideal for audio applications.

The OPA4134UAG4 is typically used in instrumentation, linear, and buffer amplifiers for high speed, low-noise applications. It is suitable for general-purpose analog instrumentation, such as line drivers, voltage followers, summing amplifiers, and differential-to-single-ended line receivers. It can also be used in operational amplifiers (op-amps) and buffer amplifiers, where it can provide excellent performance over a wide range of conditions.

The OPA4134UAG4 amplifier works in a conventional manner, amplifying voltage signals between its input and output while giving a low output impedance. It can provide gain up to 30 dB, with a wide bandwidth of 18 MHz at 1 V/μs, making it ideal for high-speed analog applications. The input and output ports are protected from over-voltage conditions and from ESD using external protection devices.

The OPA4134UAG4 provides two-resistor closed-loop feedback for precise gain regulation, along with an adjustable gain switch. It has lower noise than regular non-inverting amplifier stages, and the output includes an enhanced slew-rate limiting for better stability and faster response times.

The amplifier also features an adjustable current-optimizing input bias current, and adjustable low-drift temperature coefficients. Additionally, it offers excellent DC parameters with low offset, low drift, and a wide output voltage swing.

In summary, the OPA4134UAG4 provides a low power operation with low noise and wide bandwidth, making it ideal for linear, instrumentation, op-amps, and buffer applications. It offers excellent performance over a wide range of conditions, and its adjustable gain switch, adjustable bias current, and improved temperature coefficients make it an ideal choice for demanding audio applications.
