| BI Technologies' New Products  Providing design engineers with a means of implementing A-to-D (analog to digital) and D-to-A (digital to analog) conversions in a variety of circuits, TT electronics BI Technologies SMT Division has released a series of 8-bit and 10-bit R2R resistor ladder networks for automotive, industrial, building monitoring and process automation applications. Designated the BCN31L and 628L Series, the thick film resistive ladder networks are packaged in space-saving 2512 chips and medium small-outline surface mount packages, respectively.Additional applications for the R2R resistor ladder networks include auto calibration circuits, slope generators, function generators and motor speed control. The BCN31L Series, in 2512 chip configuration, is one of the smallest ladder networks on the market, Rieley continued. The 8-bit, 10 terminal, 2512 BCN31L Series ceramic devices feature a ladder accuracy of +/- 1/2 LSB (least significant bit). The networks have a power rating of 25mW/resistor, with a package power rating of 400mW. The 628L Series networks are available in a 16-lead SO-M body style plastic package. Ladder accuracy is +/- 1/2 LSB for the 8-bit networks and +/- 1 LSB for the 10-bit networks. Resistor power rating for the 628L devices is 40mW/resistor, with package power rating at 640mW. Resistance range for both the BCN31L and 628L networks is 1Kohm to 100Kohm and +/- 2% absolute tolerance, with TCRs to +/- 100ppm/°C. Operating temperature range is -55°C to +125°C. write your comments about the article :: © 2006 Networking News :: home page |
