THEORY OF OPERATION AND SPECIFICATIONS
Your generator kit is built around the MAX038CPP, a special-function IC at U1
which provides sinewave, squarewave, and triangle-wave output over a wide
frequency range. Op-amp U2 buffers the generator IC's output signal and
establishes adjustable DC Offset. U3 buffers the IC's VCO reference voltage to
ensure stability. Q1/Q2 provide low-Z output with short-circuit protection. All
source voltages are regulated (U4-U7).
Typical Specifications:
Power Requirements:.......................12 VAC
Frequency Range:............................1 Hz to 1 MHz in six decade ranges
Amplitude Range:............................0 to 12 volts peak-to-peak
DC Offset Range: ............................-6 volts to +6 volts
Output Impedance: ..........................400 ohms, short-circuit protected
