D/A converters feature precision DC, 1-microsecond settling time

Milpitas, Calif.—Linear Technology Corp. has introduced a family of low-power, precision 16-/14-/12-bit unbuffered voltage output A/D converters.

Both the unipolar LTC2641 and bipolar LTC2642 draw 120µA of supply current while settling to within 0.5LSB for a full-scale step in 1µs.

The voltage output A/D converters feature a 0.5nV•s glitch impulse, which is key for AC applications such as waveform generation.
The LTC2641-16 and LTC2642-16 also offer accurate DC specifications, including 16-bit monotonic resolution, ±2LSB(max) INL, ±2LSB(max) unipolar offset error, and ±5LSB(max) gain error. Additionally, these A/D converters have low drift of 0.1ppm/°C over the -40°C to +85°C industrial temperature range.

With their low offset and drift specifications, the LTC2641/LTC2642 can be used in precision DC positioning systems, gain and offset adjustment applications, automatic test equipment and data acquisition systems.

Pricing: Begins at $2.95 for the LTC2642-12 and LTC2641-12 in 1,000-piece quantities.

Availability: Now.
