The 3B34 Rev. 0 is an isolated, linearized RTD input module that amplifies, linearizes, and protects analog input voltages from a wide variety of two-, three-, and four-wire Resistor Temperature Detectors (RTDs). The module provides a constant +10V bridge excitation voltage and simultaneous precision voltage and current outputs linear to input temperature. RTD excitation current and three-wire lead resistance compensation provide a complete signal conditioning solution. The module circuitry can withstand 220V rms at the input screw-terminals. All 3B34 series modules are mix-and-match and Hot Swappable.

The AD632 is an internally-trimmed monolithic four-quadrant multiplier/divider from Analog Devices. It has a maximum multiplying error of ±0.5% without external trims. The product features excellent supply rejection, low temperature coefficients and long term stability, even under adverse conditions. The AD632 is pin-for-pin compatible with the industry standard AD532 with improved specifications and a fully differential high impedance Z-input. The AD632 is capable of providing gains of up to X10, frequently eliminating the need for separate instrumentation amplifiers to precondition the inputs. The AD632 can be effectively employed as a variable gain divider.

The AD9066 is a dual 6-bit ADC that has been optimized for low-cost in-phase and quadrature (I and Q) demodulators. Primary applications include digital direct broadcast satellite applications where broadband quadrature phase shift keying (QPSK) modulation is used. In these receivers, the recovered signal is separated into I and Q vector components and digitized. To reduce total system cost and power dissipation, the AD9066 provides an internal voltage reference and operates from a single +5 volt power supply. Digital outputs are CMOS compatible and rated to 60 MSPS conversion rates. The digital input (ENCODE) utilizes a CMOS input stage with a TTL compatible (1.4 V) threshold. The AD9066 is housed in a 28-lead SOIC and a 28-lead SSOP package and is available in two temperature grades. The AD9066JR is rated for operation over the 0°C to 70°C commercial temperature range. The AD9066AR/ARS is rated for the –40°C to +85°C industrial temperature range.
