6 / 16 page  6 LTC1064 PIN FUNCTIONS AGND (Pin 6): Analog Ground. When the LTC1064 oper- ates with dual supplies, Pin 6 should be tied to system ground. When the LTC1064 operates with a single positive supply, the analog ground pin should be tied to 1/2 supply and it should be bypassed with a 1 µF solid tantalum in parallel with a 0.1 µF ceramic capacitor, Figure 1. The positive input of all the internal op amps, as well as the common reference of all the internal switches, are inter- nally tied to the analog ground pin. Because of this, a very “clean” ground is recommended. 50/100 (Pin 17): By tying Pin 17 to V +, all filter sections operate with a clock-to-center frequency ratio internally set at 50:1. When Pin 17 is at mid-supplies, sections B and C operate with (fCLK/fO) = 50:1 and sections A and D operate at 100:1. When Pin 17 is shorted to the negative supply pin, all filter sections operate with (fCLK/fO) = 100:1. V +, V – (Pins 7, 19): Power Supplies. They should be bypassed with a 0.1 µF ceramic capacitor. Low noise, nonswitching power supplies are recommended. The de- vice operates with a single 5V supply and with dual supplies. The absolute maximum operating power supply voltage is ±8V. CLK (Pin 18): Clock. For ±5V supplies the logic threshold level is 1.4V. For ±8V and 0V to 5V supplies the logic threshold levels are 2.2V and 3V respectively. The logic threshold levels vary ±100mV over the full military tem- perature range. The recommended duty cycle of the input clock is 50%, although for clock frequencies below 500kHz, the clock “on” time can be as low as 200ns. The maximum clock frequency for ±5V supplies is 4MHz. For ±7V supplies and above, the maximum clock frequency is 7MHz. Figure 1.
