I can't understand the techno jargon ... ahhaha
<<<Cirrus Logic Unveils World's Smallest High Performance 16/20-Bit Industrial Delta-Sigma Data Converters
CLEVELAND--(BUSINESS WIRE)--Sept. 14, 1999--
New 8-Pin ADCs Deliver 5x the Throughput at Half the Price of Competitive Converters; Precisely Match Requirements for Industrial
Data Acquisition Applications
Cirrus Logic Inc. (Nasdaq:CRUS) today introduced the world's smallest and most cost-effective 16- and 20-bit Delta-Sigma analog-to-digital converters (ADCs) with a highly space-efficient 8-pin package.
The new CS551x family enables, for the first time, manufacturers of a wide range of process control equipment, temperature and pressure sensors, and handheld and medical instruments to reap all the quality, performance, and ease-of-design benefits of a single-chip, Delta-Sigma ADC solution.
The ADC family features fully differential analog inputs and an output word rate of up to 163 Hz with power consumption less than 2 milliwatts. For as little as $3 in 1000 unit quantities, these latest Crystal(R)-brand devices deliver five times the throughput of other 8-pin Delta-Sigma ADCs, at half the price.
This price/performance breakthrough -- supported by a compact pinout, easy-to-use serial interface, and 16/20-bit resolution -- makes the new converters the only 8-pin Delta-Sigma ADCs that meet the cost, performance, and time-to-market requirements of today's industrial data acquisition applications.
"Never has the global marketplace been more value sensitive," said Scott Kasin, Product Marketing Manager, Data Acquisition ICs, for Cirrus Logic's Crystal Industrial and Communications Division. "As the pioneer of Delta-Sigma technology for industrial ADCs, our company has leveraged fifteen years of design and manufacturing expertise to deliver streamlined, easy-to-use and cost effective integrated solutions. We expect our new ADC family to give our customers exactly the edge they need in today's highly competitive environment, since they'll be able to reduce design times and add value while actually lowering system cost."
High-Volume Asian Market
"Our new converters are ideally suited to serve the expanding range of data acquisition applications in the Asian market," said Kasin. He noted that "high-volume consumer applications as well as applications in digital panel meters, weigh scales and smart sensors and other industrial uses offer substantial market opportunities for the new CS551x family."
Streamlines Designs
The easy-to-use serial interface incorporated into the new ADC family can substantially reduce overall design complexity. For instance, the converters require no initialization upon start-up and provide a simple 2-wire serial interface for digital data collection. In addition, the serial interface is tolerant to logic levels in the range of 2.5 V to 5 V making it easy to interface to the new generation of low-voltage microcontrollers.
Lowers System Cost
The CS551x family offers a fully differential analog input coupled with a wide range voltage reference (250 mV to 5 V), which allows the device to interface to low level analog signals from various types of sensors without the need for external amplifiers. This significantly reduces overall system cost. In addition, the CS5511 and CS5513 family members include an on-chip oscillator, which eliminates the need for an external clock source, further reducing design complexity and system cost.
Enhances Data Integrity
The differential analog input structure also enhances EMI/RFI immunity and eliminates the effects of common-mode noise, ensuring data integrity in noisy industrial conditions. To increase accuracy and reliability the CS5510 and CS5512 incorporate a patented, modified SINC4 digital filter, which offers simultaneous rejection of 50 and 60 Hz, eliminating electrical noise sources common in industrial environments.
Low Power ADC Family
The entire CS551x family supports either single or dual power supply operation. In normal operation, a device consumes less than 2 mW and in sleep mode it consumes 10 uW, providing the size and power consumption needed for battery-life-sensitive portable devices.
Availability & Pricing
The CS551x family of 8-pin, Delta-Sigma, ADCs are sampling now with production volumes available by the end of 1999. The 16-bit (CS5510/11) devices are priced at under $3 each in quantities of 1,000 and the 20-bit (CS5512/13) solutions are priced at under $4 each in quantities of 1,000.
