MAX6950CEE+

The MAX6950CEE+ is a serially interfaced, +2.7V to +5.5V, 5-digit LED display driver in 16 pin QSOP package. This compact common cathode display driver interface microprocessors to individual 7 segment numeric LED digits, bar graph or discrete LEDs through an SPI, QSPI, MICROWIRE-compatible serial interface. It drives up to five 7 segment digits or 40 discrete LEDs. Included on-chip are hexadecimal character decoders (0–9, A–F), multiplex scan circuitry, segment, digit driver & static RAM that stores each digit. User may select hexadecimal decoding or no-decode for each digit to allow any mix of 7 segment digits, bar graph or discrete LED to be driven. The segment current for LED is set by an internal digital brightness control. Segment driver is slew rate limited to reduce EMI, individual digits may be addressed and updated without rewriting entire display. It is used in set-top boxes, panel meters, white goods, professional audio equipment, industrial controllers & instrumentation.
