LT6557IGN#PBF

Analog Devices · Video Amplifiers · SSOP-16

LT6557IGN#PBF from Analog Devices, in a SSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 EN input Enable control pin: the part is enabled when pulled low, and an internal 40k pull-up turns the part off if the pin is unconnected.
2 GND power_in Ground reference for the enable pin and the bias control voltage pin, which must be connected externally to ground.
3 IN R input Red channel input with a nominal impedance of 200kΩ when the input bias circuit is inactive (pin 16 open).
4 GND R power_in Ground of the red channel amplifier, not internally connected to other ground pins, and must be connected externally to ground.
5 IN G input Green channel input with a nominal impedance of 200kΩ when the input bias circuit is inactive (pin 16 open).
6 GND G power_in Ground of the green channel amplifier, not internally connected to other ground pins, and must be connected externally to ground.
7 IN B input Blue channel input with a nominal impedance of 200kΩ when the input bias circuit is inactive (pin 16 open).
8 GND B power_in Ground of the blue channel amplifier, not internally connected to other ground pins, and must be connected externally to ground.
9 V+ B power_in Positive supply of the blue channel amplifier, not internally connected to other supply pins, and must be externally connected to the supply bus with proper bypassing.
10 OUT B output Blue channel output.
11 V+ G power_in Positive supply of the green channel amplifier, not internally connected to other supply pins, and must be externally connected to the supply bus with proper bypassing.
12 OUT G output Green channel output.
13 V+ R power_in Positive supply of the red channel amplifier, not internally connected to other supply pins, and must be externally connected to the supply bus with proper bypassing.
14 OUT R output Red channel output.
15 V+ power_in Positive supply voltage of the control circuitry, not internally connected to other supply pins, and must be externally connected to the supply bus with proper bypassing.
16 BCV passive Bias control voltage: a resistor between pin 16 and pin 2 (GND) generates a DC input bias voltage at the three amplifier inputs for AC coupling.
