analog ICs for communications, industrial, medical and automotive
applications, expanded its comprehensive LED driver portfolio with the
AS1116, an ultra small multiplexed LED driver. The AS1116 operates
from a single 2.7V to 5.5V supply while requiring lowest supply
current of 0.6mA during operation and 200nA in shutdown mode.
The AS1116 can drive either eight 7-segment digits or 64 individual
LEDs with 47mA per digit or 5.5mA per LED. The current can be easily
adjusted by an external resistor. With an excellent accuracy of +/-3%,
the AS1116 improves picture quality of LED displays since intensity
variations between LEDs and LED modules are minimized. For either
global digital brightness control or separate dimming of each single
digit in 16 steps a 4-bit PWM is implemented.
