9 / 16 page  9 640212fa LT6402-12 VOCM (Pin 2): This pin sets the output common mode voltage. Without additional biasing, both inputs bias to this voltage as well. This input is high impedance. VCCA, VCCB, VCCC (Pins 3, 10, 1): Positive Power Supply (Normally Tied to 5V). All three pins must be tied to the same voltage. Bypass each pin with 1000pF and 0.1μF capacitors as close to the package as possible. Split supplies are possible as long as the voltage between VCC and VEE is 5V. VEEA, VEEB, VEEC (Pins 4, 9, 12): Negative Power Supply (Normally Tied to Ground). All three pins must be tied to the same voltage. Split supplies are possible as long as the voltage between VCC and VEE is 5V. If these pins are not tied to ground, bypass each pin with 1000pF and 0.1μF capacitors as close to the package as possible. +OUT, –OUT (Pins 5, 8): Outputs (Unfiltered). These pins are high bandwidth, low-impedance outputs. The DC output voltage at these pins is set to the voltage applied at VOCM. +OUTFILTERED, –OUTFILTERED (Pins 6, 7): Filtered Outputs. These pins add a series 50Ω resistor from the unfiltered outputs and three 14pF capacitors. Each output has 14pF to VEE, plus an additional 14pF between each pin (See the Block Diagram). This filter has a –3dB bandwidth of 75MHz. ENABLE (Pin 11): This pin is a TTL logic input referenced to the VEEC pin. If low, the LT6402-12 is enabled and draws typically 30mA of supply current. If high, the LT6402-12 is disabled and draws typically 250μA. +INA, +INB (Pins 15, 16): Positive Inputs. These pins are normally tied together. These inputs may be DC- or AC- coupled. If the inputs are AC-coupled, they will self-bias to the voltage applied to the VOCM pin. –INA, –INB (Pins 14, 13): Negative Inputs. These pins are normally tied together. These inputs may be DC- or AC- coupled. If the inputs are AC-coupled, they will self-bias to the voltage applied to the VOCM pin. Exposed Pad (Pin 17): Tie the pad to VEEC (Pin 12). If split supplies are used, DO NOT tie the pad to ground. PIN FUNCTIONS |
