7 Detailed Description

7.1 Overview

The LM7332 device is a rail-to-rail input and output amplifier with wide operating voltages and high-output

currents. The LM7322 is efficient, achieving 15.2-V/µs slew rate and 21-MHz unity gain bandwidth while requiring

only 2 mA of total supply current. The LM7332 device performance is fully specified for operation at 5 V, ±5 V

and ±15 V.

The LM7332 device is designed to drive unlimited capacitive loads without oscillations. The LM7332 is fully

tested at

−40°C, 125°C, and 25°C, with modern automatic test equipment. High performance from −40°C to

+125°C, detailed specifications, and extensive testing makes them suitable for industrial, automotive, and

communications applications.

Most device parameters are insensitive to power supply voltage, and this makes the parts easier to use where

supply voltage may vary, such as automotive electrical systems and battery-powered equipment. The LM7332

has a true rail-to-rail output and can supply a respectable amount of current (±70 mA) with minimal head room

from either rail (1 V).

7.3.1 Estimating the Output Voltage Swing

It is important to keep in mind that the steady-state output current will be less than the current available when

there is an input overdrive present. For steady-state conditions, Figure 47 and Figure 48 plots can be used to

predict the output swing. These plots also show several load lines corresponding to loads tied between the

output and ground. In each case, the intersection of the device plot at the appropriate temperature with the load

line would be the typical output swing possible for that load. For example, a 600-

Ω load can accommodate an

unclipped swing.
