MAX2079
Low-Power, High-Performance, Fully Integrated
Octal Ultrasound Receiver (Octal LNA, VGA,
AAF, ADC, and CWD Beamformer)
DC ELECTRICAL CHARACTERISTICS—CWD MODE (VGA, AAF, and ADC Off) (continued)
(VREF = 2.5V, VCC3 = 3.13V to 3.47V, VCC5 = 4.5V to 5.25V, VAVDD = VOVDD = 1.7V to 1.9V, TA = 0NC to +70NC, VGND = 0V,
SHDN = 0, CWD = 1, LOON = 1, RIN = 200I, high LNA gain, CI+, CI-, CQ+, CQ- pulled up to +11V through four separate 0.1%
120I resistors. No RF signals applied. Typical values are at VREF = 2.5V, VCC3 = 3.3V, VCC5 = 4.75V, VAVDD = VOVDD = 1.8V,
TA = +25NC, unless otherwise noted.) (Note 3)
