3.3V, Step-Down, Current-Mode PWM DC-DC Converters

General Description The MAX748A/MAX763A are 3.3V-output CMOS, step down switching regulators. The MAX748A accepts inputs from 3.3V to 16V and delivers up to 500mA. The MAX763A accepts inputs between 3.3V and 11V and delivers up to 500mA. Typical efficiencies are 85 to 90. Quiescent supply current

Integrated Circuit TV Sound Circuit

Description: The NTE748 is an integrated circuit in a 14–Lead DIP type pacjage designed for IF limiting, detection, audio preamplifier and driver for the sound portion of a TV receiver. Features: ● Excellent Limiting with 80µV(rms) Input Signal typ ● Large Output–Voltage Swing–to 3.5V(rms) typ

PRECISION SINGLE OPERATIONAL AMPLIFIER

DESCRIPTION The UA748 is a general purpose operational amplifier built on a single silicon chip. The resulting close match and tight thermal coupling gives low offsets and temperature drift as well as fast recovery from thermal transients. ■ INPUT OFFSET VOLTAGE : 3mV max. OVER TEMPERATURE ■ FR
