Maxim Integrated produces a wide variety of amplifiers for various applications, including instrumentation, OP Amps, buffer amplifiers, and linear amplifiers. The MAX5167MCCM+ is one of its recent offerings, designed for precision current-sense applications in single-supply, low-power-consumption, and low-noise applications. This device is particularly suited for low-voltage and battery-operated applications due to its low-power consumption and small package size.

The MAX5167MCCM+ is a single high-speed, low-bias current-sense amplifier with a fixed gain of +20 V/V. It offers excellent common-mode rejection ratios (CMRR) of 86 dB at DC to 53 dB at 2 MHz, along with 0.002% DC offset, 0.0003% gain error, and 0.002% line regulation. This makes the chip suitable for accurate and precise current sensing as compared to traditional sense amplifiers that use CMMR, gain error, and offset inconsistency. It also has a total harmonic distortion (THD) of 0.0004%.

The device operates on a single supply voltage ranging from 2.7V to 5.5V, and features a wide bandwidth of 10MHz with an input to output delay of 75ns. The device is typically used together with the MAX4545A voltage-to-current converter to detect positive and negative currents. The voltage-to-current converter has an input impedance of 750 Ohms, making it very suitable for precision current-sense applications.

The MAX5167MCCM+ also features a temperature-compensated temperature-independent bias current, making it very suitable for use in low-voltage and battery-powered applications. It also has a low input current of 0.125 uA, making it suitable for advanced low-noise, low-power precision circuits. Furthermore, the current-sense amplifier is immune to power supply noise and transients due to its high PSRR of 130 dB at 1 kHz.

In summary, the MAX5167MCCM+ is a highly advanced and versatile current-sense amplifier suitable for a wide variety of applications, including instrumentation, OP amps, buffer amplifiers, and linear amplifiers. It offers excellent performance in terms of CMRR, gain error, line regulation, and THD. It operates on a single supply voltage ranging from 2.7V to 5.5V and features a wide bandwidth with an input to output delay of 75ns. The device also features a low input current and high PSRR, making it very suitable for low-voltage and battery operated applications.
