Description

The FAN4174 (single) and FAN4274 (dual) are voltage

feedback amplifiers with CMOS inputs that consume

only 200 µA of supply current per amplifier, while

providing ±33 mA of output short-circuit current. These

amplifiers are designed to operate 5 V supplies. The

common mode voltage range extends beyond the

negative and positive rails.

The FAN4174 and FAN4274 are designed on a CMOS

process and provide 3.7 MHz of bandwidth and 3 V / μs

of slew rate at a supply voltage of 5 V.

These amplifiers operate and are reliable over a wide

temperature range of -40°C to +125°C.

The combination of extended temperature operation,

low power, rail-to-rail performance, low-voltage

operation, and a tiny package optimize this amplifier

family for use in many industrial, general-purpose, and

battery-powered applications.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Functional operation under any of these conditions is NOT implied.

General Description Overdrive Recovery The FAN4174 amplifier includes single-supply, generalpurpose, voltage-feedback amplifiers, fabricated on a biCMOS process. The family features a rail-to-rail input and output and is unity gain stable. The typical noninverting circuit schematic is shown in Figure 21. Overdrive of an amplifier occurs when the output and/or input ranges are exceeded. The recovery time varies based on whether the input or output is overdriven and by how much the range is exceeded.

General layout and supply bypassing play major roles in high-frequency performance. Fairchild evaluation boards help guide high-frequency layout and aid in device testing and characterization. Follow the steps below as a basis for high-frequency layout: 1. Include 6.8 μF and 0.01 μF ceramic capacitors. 2. Place the 6.8 μF capacitor within 19.05 mm (0.75 inches) of the power pin. 3. Place the 0.01 μF capacitor within 2.54 mm (0.1 inches) of the power pin. 4.
