ELECTRICAL CHARACTERISTICS (continued)
(PVDD = SVDD = +5V, PGND = SGND = 0V, SHDN = SVDD, C1 = C2 = 1F, RL =
∞, resistive load referenced to ground, for
MAX9722A gain = -1V/V (RIN = RF = 10k
Ω), for MAX9722B gain = -2V/V (internally set), TA = -40°C to +85°C, unless otherwise noted.
Typical values are at TA = +25°C, unless otherwise noted.) (Note 1)
Note 1: All specifications are 100% tested at TA = +25
°C; temperature limits are guaranteed by design.
Note 2: Gain for the MAX9722A is adjustable.
Note 3: The amplifier inputs are AC-coupled to ground through CIN_.
Note 4: Measurement bandwidth is 22Hz to 22kHz.
