Data Acquisition ADCs/DACs - Specialised Polyphase Multifunction Energy Meter IC

The ADG636 is a monolithic device, comprising two indepen-dently selectable CMOS single pole, double throw (SPDT) switches. When on, each switch conducts equally well in both directions.The ADG636 operates from a dual ±2.7 V to ±5.5 V supply, or from a single supply of +2.7 V to +5.5 V.This switch offers ultralow charge injection of ±1.5 pC over the entire signal range and leakage current of 10 pA typical at 25°C. In addition, it offers on resistance of 85 Ω typical, which is matched to within 2 Ω between channels. The ADG636 also has low power dissipation yet is capable of high switching speeds.The ADG636 exhibits break-before-make switching action and is available in a 14-lead TSSOP package.Product HighlightsUltralow charge injection.

The ADG5408/ADG5409 are monolithic CMOS analog multiplexerscomprising eight single channels and four differentialchannels, respectively. The ADG5408 switches one of eightinputs to a common output, as determined by the 3-bit binaryaddress lines, A0, A1, and A2. The ADG5409 switches one offour differential inputs to a common differential output, asdetermined by the 2-bit binary address lines, A0 and A1.An EN input on both devices enables or disables the device.When EN is disabled, all channels are switched off. The on-resistanceprofile is very flat over the full analog input range, whichensures good linearity and low distortion when switching audiosignals. High switching speed also makes the parts suitable forvideo signal switching.Each switch conducts equally well in both directions when on,and each switch has an input signal range that extends to the powersupplies. In the off condition, signal levels up to the suppliesare blocked.The ADG5408/ADG5409 do not have a VL pins; rather, the logic powersupply is generated internally by an on-chip voltage generator.Product Highlights  Trench isolation guards against latch-up. A dielectric trench separates the P and N channel transistors thereby preventing latch-up even under severe overvoltage conditions.  Low RON.  Dual-supply operation. For applications where the analog signal is bipolar, the ADG5408/ADG5409 can be operated from dual supplies up to ±22 V.  Single-supply operation. For applications where the analog signal is bipolar, the ADG5408/ADG5409 can be operated from a single-rail power supply up to 40V.  3 V logic-compatible digital inputs: VINH = 2.0 V, VINL = 0.8 V.  No VL logic power supply required.Applications Relay replacement  Automatic test equipment  Data acquisition  Instrumentation  Avionics Audio and video switching  Communication systems

The AD8333 is a dual-phase shifter and I/Q demodulator that enables coherent summing and phase alignment of multiple analog data channels. It is the first solid-state device suitable forbeamformer circuits, such as those used in high performance medical ultrasound equipment featuring CW Doppler. The RF inputs interface directly with the outputs of the dual-channel, low noise preamplifiers included in the?AD8332.A divide-by-4 circuit generates the internal 0? and 90? phases of the local oscillator (LO) that drive the mixers of a pair of matched I/Q demodulators.The AD8333 can be applied as a major element in analog beamformer circuits in medical ultrasound equipment.The AD8333 features an asynchronous reset pin. When used in arrays, the reset pin sets all the LO dividers in the same state. Sixteen discrete phase rotations in 22.5? increments can be selected independently for each channel. For example, if Channel 1 is used as a reference and the RF signal applied to Channel 2 has an I/Q phase lead of 45?, Channel 2 can be phase aligned with Channel 1 by choosing the correct code.Phase shift is defined by the output of one channel relative to another. For example, if the code of Channel 1 is adjusted to 0000 and that of Channel 2 to 0001 and the same signal is applied to both RF inputs, the output of Channel 2 leads that of Channel 1 by 22.5?.The I and Q outputs are provided as currents to facilitate summation. The summed current outputs are converted to voltages by a high dynamic-range, current-to-voltage (I-V) converter, such as the AD8021, configured as a transimpedance amplifier. The resultant signal is then applied to a high resolution ADC, such as the AD7665 (16 bit/570 kSPS).The two I/Q demodulators can be used independently in other nonbeamforming applications. In that case, a transimpedance amplifier is needed for each of the I and Q outputs, four in total for the dual I/Q demodulator.The dynamic range is 159 dB/Hz at each I and Q output, but the following transimpedance amplifier is an important element in maintaining the overall dynamic range, and attention needs to be paid to optimal component selection and design.The AD8333 is available in a 32-lead LFCSP (5 mm ? 5 mm) package for the industrial temperature range of ?40?C to +85?C.Applications Medical imaging (CW ultrasound beamforming) Phased array systems (radar and adaptive antennas) Communication receivers
