CS4340A
4. CHARACTERISTICS AND SPECIFICATIONS Typical performance characteristics are derived
from measurements taken at TA = 25 °C, VA = 3.3 V and VA = 5.0 V. Min/Max performance characteristics are
guaranteed over the specified operating temperature and voltages.)
ANALOG CHARACTERISTICS (CS4340A-KS) (Test conditions (unless otherwise specified):
Input test signal is a 997 Hz sine wave; measurement bandwidth is 10 Hz to 20 kHz; test load RL = 10 kΩ, CL = 10
pF (see Figure 7).)
