(1)

Calculated value from Voltage Gain test on each channel.

(2)

Linearity Error is the variation in dc gain from VIN = 1.0V to VIN = 3.5V.

(3)

Input from signal generator: tr, tf < 1 ns.

AC Test Circuit

Note: 8 pF load includes parasitic capacitance.

Figure 3. Test Circuit (One Channel)

Figure 3 shows a typical test circuit for evaluation of the LM2470. This circuit is designed to allow testing of the

LM2470 in a 50

Ω environment without the use of an expensive FET probe. The two 2490Ω resistors form a

200:1 divider with the 50

Ω resistor and the oscilloscope. A test point is included for easy use of an oscilloscope

probe. The compensation capacitor is used to compensate the stray capacitance of the two 2490

Ω resistors to

achieve flat frequency response.
