With resolutions ranging from 16- to 24-bits, use these ADCs for your most demanding measurement designs. Thermocouple / Temperature Measurement Cirrus offers the industry’s most complete data acquisition solutions for thermocouple design. The CS552X family includes a low input current, chopper-stabilized, instrumentation amplifier integrated with multi-channel ∆Σ ADCs, which use charge-balance techniques to achieve 16-bit (CS5521/23) and 24-bit (CS5522/24/28) performance. The CS552X family is available in two-channel (CS5521/22), four-channel (CS5523/24), or eight-channel (CS5528) configurations. Selectable inputs of 25 mV, 55 mV, 100 mV, 1V, 2.5 V, and 5 V are easily achieved using the on-chip PGIA (programmable gain instrumentation amplifier). For ground-based thermocouple applications, the devices include a charge pump drive, which applies a negative voltage bias to on-chip amplifiers. Designed to precisely measure temperature, pressure, chemical composition, current or voltage, these highly integrated single-supply ADCs are ideal for applications that require both primary and secondary measurements. Target applications include process indicators, thermocouples, digital thermometers, blood gas analyzers, fetal oxygen saturation systems and other industrial and medical applications. Weigh Scale / Load Cell The CS5516 and CS5520 are the most complete ADC solutions available today for digitizing low-level signals from strain gauges, load cells, and pressure transducers. With an on-chip PGIA, choice of DC or AC bridge excitation, and software selectable reference and signal demodulation, the CS5516 uses ∆Σ modulation to achieve 16-bit resolution at output word rates up to 60 Hz. The CS5520 achieves 20-bit resolution at word rates up to 60 Hz. Both ADCs include system calibration to null offset and gain errors in the input channel. The digital values associated with the system calibration can be written to, or read from, the calibration RAM locations at any time via the serial communications port. The 4-bit DC offset DAC, in conjunction with digital correction, is initially used to zero the input offset value. The CS553X family of ADCs is also ideal for weigh scale applications. They are optimized for measuring low-level unipolar or bipolar signals and use charge-balance techniques to achieve 16-bit (CS5531/33) and 24-bit (CS5532/34) performance. A simple, 3-wire serial interface (SPI and Microwire compatible) with Schmitt Trigger inputs is provided for microcontroller communications. High dynamic range, programmable output rates, and flexible power supply options make these ADCs ideal for your next weigh scale design. Bridge Transducer Application (Force & Pressure) / Weigh Scale Application CS5516 CS5531 CS5533 CS5520 CS5532 CS5534 Load Cell MUX PGIA ∆Σ Digital Filter Serial Interface Leading the Digital Entertainment Revolution ™ System µC 1 DC Measurement GPS System The CS5523 ∆Σ ADC and the EP7311 embedded processor are ideally suited for Global Positioning System (GPS) designs. The CS5523 ∆Σ ADC simplifies implementing a still compass for your GPS design. Using charge-balance techniques to achieve 16-bit performance, this four-channel IC includes a low input current, chopper-stabilized, instrumentation amplifier. Selectable inputs of 25 mV, 55 mV, 100 mV, 1 V, 2.5 V, and 5 V are easily achieved using the on-chip PGIA. A fourth-order ∆Σ modulator followed by a digital filter provides eight selectable output word rates. The digital filter is designed to settle to full accuracy within one conversion cycle and when operated at word rates below 30 Hz, they reject both 50 and 60 Hz interference. These single supply products are ideal solutions for measuring isolated and non-isolated, low-level signals. The small form factor and ultra-low power operation of the EP7311 embedded processor makes it perfect for Global Positioning System (GPS) designs. Core-logic functionality of this system-on-chip is built around an ARM720T processor running at clock speeds up to 74 and 90 MHz with 8 KB of four-way, set-associative, unified cache and a write buffer. An enhanced memory management unit is incorporated into the ARM720T, which allows for support of popular operating systems like Microsoft Windows CE and Linux. The EP7311 operates at 2.5 V, while its I/O accommodates a 2.5 to 3.3 V range. The device has three basic power states: operating, idle, and standby. You can easily create a low power system solution by simply adding the desired memory and peripherals. All necessary interface logic is integrated on-chip. You can’t get lost with a Cirrus industrial chip. Ethernet Ethernet (per IEEE 802.3 standard) is the most widely adopted standard for LAN communications over either coaxial or twisted pair cable, typically runs at 10 Mbps, though speedier systems can transfer data at 100 Mbps, and even at 1 gigabit or more. Cirrus offers two powerful embedded Ethernet solutions for industrial connectivity communications, the CS8900A Controller and the CS8952T Transceiver. The CS8900A is optimized for use within 10Base-T networks and the CS8952 is an ideal choice as either 10Base-T or 10Base-TX transceiver. Each device delivers unmatched price/performance and flexibility because they eliminate the need for external components and are adaptable to a broad range of industrial LAN applications. 2 www.cirrus.com The CS8900 has emerged as a de facto standard for embedded Ethernet control, demonstrating its industrial-strength performance in Internet phones, industrial controllers, ADSL systems, CNC machines, point-of sale equipment for gas stations, and undersea data gathering equipment. The CS8952T has won strong acceptance as OEMs increasingly migrate to machines that communicate with other machines, giving rise to a critical need for Fast Ethernet transceivers to operate reliably in highnoise environments. It combines analog and digital processing onto a single chip to deliver high performance in critical areas of noise immunity, near end crosstalk (NEXT) margin, transmitter jitter, and power/receiver performance. Energy Measurement Cirrus offers cost effective, highly optimized energy measurement solutions. Utility providers and power meter manufacturers are using our energy measurement technology to replace electromechanical power meters with more efficient digital electronic versions. The CS5460A, CS5451 and CS5471 use Cirrus’ high performance analog front-end (AFE) technology to achieve extremely accurate energy measurements. In addition, the CS5460A provides an on chip calculation engine and preventive maintenance features such as power surge detection and identification of irregular power fluctuations. The three “energy to digital” converters are the perfect choice for manufacturers of exact energy management solutions, such as, power meters, home appliances and industrial equipment.

Our innovative solutions enhance performance for a wide variety of T1/E1/J1 LIU and LAN applications without sacrificing features that improve system diagnostics. T1/E1/J1 LIUs (Line Interface Unit) The CS61884, Octal, E1/T1/J1 short-haul LIU enables portdense applications for the worldwide E1, North American T1 and Japanese J1 markets. The CS61884 builds on Cirrus’ patented matched impedance technology, which completely eliminates the need to change external components between 75-ohm, 100-ohm and 120-ohm mode designs. The simplified, single circuit design reduces component count, the manufacturing bill of materials (BOM) and allows manufacturers to support all major international telecommunications protocol standards in one “universal T1, E1, J1” functional line card. The CS61884 integrates eight full-featured LIU channels in an industry standard footprint and firmware compatible IC. Each channel has complete receiver and transmitter circuitry with crystal-less path-selectable jitter attenuation, full encoder/ decoder circuitry, loss of signal detection, and alarm indication signal warnings. An arbitrary waveform generator allows user-customized transmit pulse shapes. Three volt, I/O provides lower power consumption versus other competitive port-dense products. Each channel provides internal AMI/B8ZS/HDB3 encoding/ decoding and crystal-less jitter attenuation that complies with the most stringent standards. The CS61884 supports both 1.544 Mbps and 2.048 Mbps data transmission and enhanced system diagnostics. Channel zero can be configured for G.772 non-intrusive monitoring of any of the other seven channels’ transmit paths. Cirrus also offers the industry’s smallest dual T1/E1 LIU, the CS61584A, with a package area-per-port of only 68 square millimeters. This device delivers compelling performance in a small form factor for a host of industrial applications including data channel banks/concentrators, T1/E1 multiplexers, DACS, and SONET/SDH multiplexers.
