ELECTRICAL CHARACTERISTICS (continued)
(VAVDD = 18V, VAVDD_AMP = VREF = 18V, VDVDD = 3.3V, VGND = VAGND_AMP = 0, VCOM = VCOM_FB, no load, TA = TMIN to TMAX,
unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)

Note 1: All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by design.
Note 2: Thermal pad attached to multilayered board. Exceeding this limit may cause the thermal shutdown to trip.
Note 3: Measured with the VCOM amplifier configured as an inverting unity-gain amplifier (RS = RF = 1kΩ).
Note 4: CB is in pF.
