MYOWARE 2.0

Supply Voltage:
min. = 2.27V,
typ. = +3.3V or +5V,
max. = +5.47V

Input Bias Current:
250 pA, max 1 nA

Input Impedance:
800

Common Mode Rejection Ratio (CMMR):
140 dB

Ideal Gain Equation:
Raw (RAW): G = 200
Rectified (RECT): G= 200
Envelope (ENV): G = 200 * R / 1 kOhm
R is the resistance of the gain potentiometer in kOhm
