MAX4338EUB-T

The MAX4338EUB-T is an ultra-low power, rail-to-rail input/output single and dual op amp. This device was designed to provide high performance with minimal power consumption in. It features the MAX4338 National Semiconductor\'s dual noise-canceling input buffer, which is paired with a rail-to-rail output driver. The ultra-low-power operation, combined with rail-to-rail output drive capability makes this op amp applicable to a wide range of instrumentation, OP Amps, and Buffer Amps applications.

Application Fields

The MAX4338EUB-T is a versatile and cost-effective op amp that can be used for a wide range of applications, from low-power applications such as microphone preamps to high-power applications such as headphones and speaker amplifiers. The low-noise input buffer and rail-to-rail output driver makes the MAX4338EUB-T capable of providing stable and precise performance even in high-noise environments. Additionally, the ultra-low power operation makes this device ideal for battery-powered applications. As a result, the MAX4338EUB-T is well suited for in-car audio and medical applications.

Working Principle

The MAX4338EUB-T is a dual op amp that uses National Semiconductor\'s proprietary noise-canceling input buffer. The input buffer consists of two transconductance stages. Each stage amplifies the signal before sending it to an input resistor. As the two stages cancel each other\'s noise, they essentially act as a \'low-noise amplifier,\' producing a very low-noise signal at the output. The device also has a rail-to-rail output driver that enables the device to drive different loads. The op amp also has a slew-rate of 28V/us, a high bandwidth of 850kHz, and a very low supply current of 3.2μA (typical).

Overall, the MAX4338EUB-T provides low-power operation and low-noise performance, making it ideal for applications such as instrumentation, OP amps, and buffer amps. The dual noise-canceling input buffers, combined with a rail-to-rail output driver, make the device suitable for a wide range of applications, from low power to high-power.
