DESCRIPTION
The BUF04701 is a 4-channel, low-power, high-voltage rail-
to-rail input/output buffer. Operating on supplies ranging from
3.5V to 12V (±1.75V to ±6V), the BUF04701 has a 3dB
bandwidth of 8MHz with a slew rate of 10V/µs, and requires
only 1.1mA quiescent current. The BUF04701 features rail-
to-rail input and output capability, giving maximum dynamic
range at any supply voltage.
Featuring fast slewing and settling times, as well as a high
output drive, the BUF04701 is ideal for use as a voltage
reference buffer in Thin Film Transistor Liquid Crystal Dis-
plays (TFT-LCDs).
The BUF04701 is available in an MSOP-10 package, provid-
ing the smallest footprint and thinnest package option avail-
able, as well as the TSSOP-14 package with a pinout that
corresponds to standard quad op amps. This makes it easy to
replace quad op amps in existing LCD displays with the low
cost BUF04701, without changing the layout. The BUF04701
operates over a temperature range of –40°C to +125°C.
