BUF04701

SBOS214B – SEPTEMBER 2001 – REVISED JULY 2004

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.
