OUTPUT AMPLIFIERS

DESCRIPTION

The LLV321 is a single, low cost and voltage feedback amplifier, that

consumes only 80μA supply current, 1.2MHz of bandwidth and 1.5V/μs

of slew rate at a low supply voltage of 2.7V. It is supplied from 2.7V

(±1.35V) to 5.5V (±2.75V). The common mode voltage range extends

below the negative rail and the output provides rail-to-rail performance.

The LLV321 is fabricated on a CMOS process. The combination of

low power, rail-to-rail performance, low voltage operation, and tiny

package options makes the device well suited for use in personal

electronics equipment such as cellular handsets, pagers, PDAs, and

other battery powered applications.

The LLV321 is also applied in portable test instruments, telephone

systems, low cost general purpose applications, cellular phones, MP3

players, personal data assistants, A/D buffer, DSP interface, audio

applications, smart card readers, keyless entry, Infrared receivers for

remote controls, digital still cameras and hard disk drives.
