LTC6995-1/LTC6995-2 PIN FUNCTIONS (DCB/S6) GND (Pin 5/Pin 2): Ground. Tie to a low inductance ground 30Ω. When driving an LED or other low impedance load plane for best performance. a series output resistor should be used to limit source/ OUT (Pin 6/Pin 6): Oscillator Output. The OUT pin swings sink current to 20mA. from GND to V+ with an output resistance of approximately BLOCK DIAGRAM (S6 Package Pin Numbers Shown) 5 V+ R1 POL BIT DIV 4-BIT A/D DIGITAL 4 CONVERTER FILTER R2 MASTER OSCILLATOR 1µs V t SET • MCLK FIXED MASTER = PROGRAMMABLE OUT 50kΩ ISET DIVIDER OUTPUT DIVIDER 6 ÷ 1024 POLARITY ÷1, 8, 64, 512 tOUT 4096, 215, 218, 221 HALT OSCILLATOR DIVIDER OUTPUT RESET IF ISET < 500nA ISET POR + – LTC6995-2 + ONLY VSET = 1V – 1V SET GND RST 3 2 1 699512 BD ISET RSET Rev.
