Voltage divider with tight tolerance

20 August 2008 Analogue, Mixed Signal, LSI

Vishay's new VFCD1505 is a surface-mount flip chip voltage divider, which provides a low absolute TCR of ±0,05 ppm/°C from 0°C to +60°C and ±0,2 ppm/°C from -55°C to +125°C, +25°C reference, an excellent PCR tracking of ±5 ppm at rated power, and a load life stability ratio of ±0,005%.

The device provides tight tolerance matching of ±0,01% (available down to ±0,005%) and TCR tracking of 0,1 ppm/°C between two resistors simultaneously etched on one piece of foil on a common substrate. For designers, the electrical specifications of this integrated construction offer improved performances and better real estate utilisation over discrete resistors and matched pairs.

Applications for the new device include high-precision instrumentation amplifiers, bridge networks, differential amplifiers, and ratio arms in bridge circuits for ultra-stable and high-reliability products, such as medical, test and military equipment. Screening in accordance with EEE-INST-002 is available (MIL-PRF 55342).

The VFCD1505 has a load-life stability ratio of ±0,005% for 2000 hours at +70°C; a power rating of 0,1 W at +70°C (divided between the two resistors proportionally to their value); a low voltage coefficient less than 0,1 ppm/V; current noise of less than -40 dB; and thermal EMF of 0,05 μV/°C. It offers a fast rise time of 1,0 ns without ringing and features a non-inductive, non-capacitive design.
