MAX410/MAX412/MAX414 19-4194 Rev 6 9/09 Single/Dual/Quad, 28MHz, Low-Noise, Low-Voltage, Precision Op Amps General Description Features The MAX410/MAX412/MAX414 single/dual/quad op Voltage Noise: 2.4nV/Hz (max) at 1kHz amps set a new standard for noise performance in 2.5mA Supply Current Per Amplifier high-speed, low-voltage systems. Input voltage-noise Low Supply Voltage Operation: 2.4V to 5V density is guaranteed to be less than 2.4nV/ Hz at 1kHz. A unique design not only combines low noise 28MHz Unity-Gain Bandwidth with 5V operation, but also consumes 2.5mA supply 4.5V/s Slew Rate current per amplifier. Low-voltage operation is guaran- teed with an output voltage swing of 7.3V into 2k 250V (max) Offset Voltage (MAX410/MAX412) P-P from 5V supplies. The MAX410/MAX412/MAX414 also 115dB (min) Voltage Gain operate from supply voltages between 2.4V and 5V Available in an Ultra-Small TDFN Package for greater supply flexibility. Unity-gain stability, 28MHz bandwidth, and 4.5V/s Ordering Information slew rate ensure low-noise performance in a wide vari- PART TEMP RANGE PIN-PACKAGE ety of wideband and measurement applications.

In order to minimize noise in the input stage, current- limiting resistors are not used. If differential input voltages exceeding 1.0V are applied, limit input current to 20mA. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ELECTRICAL CHARACTERISTICS (V+ = 5V, V- = -5V, T = +25C, unless otherwise noted.)
