Santa Clara, CA--September 27, 1996--Adding to its family of rail-to-rail op amps, National Semiconductor Corp. (Santa Clara, CA) introduced a single-supply op amp for space-constrained applications.
The new device combines rail-to-rail I/O with the widest operating voltage range--1.8V to 32V--currently available in a grain-sized SOT 23-5 TinyPak package.
Due to the combination of output short circuit current of 9.8mA, THD (total harmonic distortion) of 0.006 percent and 4MHz GBW (gain bandwidth), the device drives heavy loads with low distortion, making it well suited for stand-alone or integrated modems.
For portable bar code scanners requiring high gain with reasonable bandwidth at lower power, the device offers 4MHz GBW, low 0.72mA supply current, and operating voltages as low as 1.8V. Conversely, its operation up to 32V also serves well the high-voltage requirements of industrial power supplies.
The LM7301 can be driven by voltages in excess of both power supply rails, eliminating concerns over exceeding the common mode voltage range.
Other features include a high capacitive load drive of 1,000pF, high PSRR (power supply rejection ratio) of 104dB, high CMRR (common mode rejection ratio) of 93dB and gain of 97dB. The device operates over the industrial temperature range of -40 to +85 degrees C.
Available now, the LM7301 is priced at $0.78 per1000-unit in the plastic five-lead SOT-23 TinyPak or 8-lead SOT-8 package.
