Analog Devices introduced a JFET (junction field effect transistor)-input op amp (operational amplifier) and a family of low power voltage references that have been optimized to achieve high precision, small footprint and low power consumption for industrial and instrumentation applications.

Analog Devices’ ADR12x family of low-power voltage references combines high precision and low-voltage operation within a small TSOT-23 package. The devices feature low drift performance (9 ppm per degree C) over the extended industrial temperature range (–40 degrees C to +125 degrees C)and requires a supply current of 85 µA for operation. The ADR12x are suitable for automotive electronics applications such as battery monitoring and engine control units.

The ADA4000-1 has low input bias current of 10 pA max, addressing the needs of applications, such as photodiode amplifiers. Operating on a supply voltage from ±5 V to ±15 V, the device features input offset voltage of 1 mV and low noise of 15 nV/rt Hz. Bandwidth is 6 MHz; and the slew rate is 20 V/µs.

The ADA4000-1 is sampling now and will be available in production quantities in March 2006. Dual and quad versions will be available in the first half of 2006. The ADA4000-1 is fully specified over the extended industrial temperature range of –40 degrees C to +125 degrees C, and is packaged in both a 5-lead TSOT-23 and 8-lead SOIC. Pricing is $0.91 per unit in 1,000-piece quantities.

The ADR12x family, including the ADR127 (1.25 V), ADR121 (2.5 V) and ADR125 (5.0 V) are sampling now and will be available in full production quantities in January 2006. Available in 6-lead TSOT-23 packaging, each device is priced at $1.19 per unit in 1,000 piece quantities.
