JFET op-amp targets semiconductor test apps

NEC Electronics' JFET-class dual operational amplifier for IC test applications, the PC835, touts a high slew rate, a capacitive load capability that is four times higher than competing products, and a small package (3-by-3mm TSSOP) for IC, memory, SoC and logic test equipment.

"We recognized the need for designers to have an op amp designed specifically to meet the unique needs of semiconductor test equipment and responded with the PC835," said Bart Ladd, general manager for NEC Electronics' standard solutions strategic business unit. "This product provides the high slew rates, high capacitive loads and small size necessary to power the test equipment used to verify next-generation semiconductors."

The PC835 provides stable operation for a 4,000pF load, thus allowing designers to test for higher capacitive loads per channel and a wider variety of ICs with different capacitances. Its slew rate is 9V/s to enable more precise measurements, while the small TSSOP can be used in compact, dense designs where large arrays are required. The op amp also features low input offset of 3mV maximum.

The op amp is priced at $1.20 each in sample quantities. Volume production is scheduled to begin in October. Pricing and availability are subject to change.
