LM4702 stereo hifi audio power amplifier driver 150V

Dual High Fidelity Audio Power Amp Driver IC.
Power Amp building block, requires only output stage transistors to complete a low-distortion low-noise audio amplifier.
Resulting amplifiers have scaleable output power, and can deliver up to 300W per channel, single-ended, into 8 ohms with 10% supply rail headroom and 20% rail regulation at +/- 75V rails.
150V supply ( +/- 75V rails ), 0.001% THD, 112dB S/N ratio, 110dB PSRR
Voltage designation suffix of this part is "-C", 150V supply designation
This is the ideal way to implement an integrated power amp: all the complexity of the front end differential stages, voltage gain stages, and level shifting in an IC, leaving the power output devices external, for scaleability and thermal flexibility.
This IC represents a virtually ideal power amp, however it has a relatively low output current, which requires a high gain output stage.
Output transistors can be Darlingtons, or Darlingtons implemented with discretes (discrete devices connected in Darlington configuration).
US: $3.75 Canada: $4.50 International: $5.50 Lowest cost option.
Our S&H structure is as follows:
2-nd item: S&H 75% less than first (or 25% of first)
items 3-5: S&H 80% less than first (or 20% of first)
items 6-10: S&H 90% less than first (or 10% of first)
If the S&H cost for a second item is more than 40% of the S&H of the first item, chances are the seller is making profits from S&H.
