10 / 24 page LTC6406 10 6406fb SHDN (Pin 1/Pin 7): When SHDN is floating or directly tied to V+, the LTC6406 is in the normal (active) operat- ing mode. When the SHDN pin is connected to V–, the LTC6406 enters into a low power shutdown state with Hi-Z outputs. V+, V– (Pins 2, 10, 11 and Pins 3, 9, 12/Pins 3, 6): Power Supply Pins. It is critical that close attention be paid to supply bypassing. For single supply applications it is recommended that a high quality 0.1μF surface mount ceramic bypass capacitor be placed between V+ and V– with direct short connections. In addition, V– should be tied directly to a low impedance ground plane with minimal routing. For dual (split) power supplies, it is recommended that additional high quality, 0.1μF ceramic capacitors are used to bypass V+ to ground and V– to ground, again with minimal routing. For driving large loads (<200 Ω), additional bypass capacitance may be needed for optimal performance. Keep in mind that small geometry (e.g. 0603 or smaller) surface mount ceramic capacitors have a much higher self resonant frequency than do leaded capacitors, and perform best in high speed applications. VOCM (Pin 4/Pin 2): Output Common Mode Reference Voltage. The voltage on VOCM sets the output common mode voltage level (which is defined as the average of the voltages on the +OUT and –OUT pins). The VOCM voltage is internally set by a resistive divider between the supplies, developing a default voltage potential of 1.25V with a 3V supply. The VOCM pin can be overdriven by an external voltage capable of driving the 18k Ω Thevenin equivalent impedance presented by the pin. The VOCM pin should be bypassed with a high quality ceramic bypass capacitor of at least 0.01μF, to minimize common mode noise from being converted to differential noise by impedance mismatches both externally and internally to the IC. VTIP (Pin 5/NA): This pin can normally be left floating. It determines which pair of input transistors (NPN or PNP or both) is sensing the input signal. The VTIP pin is set by an internal resistive divider between the supplies, developing a default 1.55V voltage with a 3V supply. VTIP has a Thevenin equivalent resistance of approximately 15k and can be overdriven by an external voltage. The VTIP pin should be bypassed with a high quality ceramic bypass capacitor of at least 0.01μF. See the Applications Information section for more details. +OUT, –OUT (Pins 7, 14/Pins 4, 5): Unfiltered Output Pins. Besides driving the feedback network, each pin can drive an additional 50 Ω to ground with typical short- circuit current limiting of ±55mA.
