MPA4609 quad differential i/o ultra low noise opamp X10
2x1 multiplexed High Gain Preamp OpAmp
4 differential outputs / 2 sets of 4 differential inputs
The MPA4609 is one of the lowest noise, fixed gain, 5V
single-supply, differential amplifiers available for amplification
of low-level signals in a variety of system applications.
The chip has two sets of four differential input, low-noise
amplifiers that are routed to four output stages. Two standard
logic input select lines control which set of four input preamps
are active. For applications such as tape recorders, four
heads in forward and four heads in reverse can be selected
The quad consists of eight differential low noise (0.65nV Hz)
voltage preamps. Two select lines control two pairs of inputs.
