I just received literature for two interesting new operational amplifiers.

The first is the AD827 from Analog Devices. It is a high speed, low power
dual op amp, NC1458 pin compatible. With 300V/uS slew rate, and 50 MHz
unity gain bandwidth, it looks useful.

The other is the PMI OP-260. It is a current-feedback design;  it was also 
designed to "plug in" to many circuits that were designed around voltage 
feedback op-amps. It boasts 1000V/uS slew rate, with 90MHz bandwidth at 
unity gain. It is also available in MC1458 pin compatible package.

Both applications list DAC output buffering; I bet either would be 
excellent for replacing DAC buffers in Magnavox CD players.

If you want more info, send me a message.
