The AD4630-24 is a two-channel, simultaneous sampling, Easy Drive, 2 MSPS successive approximation register (SAR) analog-to-digital converter (ADC). With a guaranteed maximum ?0.9 ppm INL and no missing codes at 24-bits, the AD4630-24 achieves unparalleled precision from ?40?C to +125?C. Figure 1 in the data sheet shows the functional architecture of the AD4630-24.A low-drift, internal precision reference buffer eases voltage reference sharing with other system circuitry. The AD4630-24 offers a typical dynamic range of 106 dB when using a 5 V reference. The low noise floor enables signal chains requiring less gain and lower power. A block averaging filter with programmable decimation ratio can increase dynamic range up to 153 dB. The wide differential input and common mode ranges allow inputs to use the full ?VREF range without saturating, simplifying signal conditioning requirements and system calibration. The improved settling of the Easy Drive analog inputs broadens the selection of analog front-end components compatible with the AD4630-24. Both single-ended and differential signals are supported.The versatile Flexi-SPI serial interface eases host processor and ADC integration. A wide data clocking window, multiple SDO lanes, and optional dual data rate (DDR) data clocking can reduce the serial clock to 10 MHz while operating at a sample rate of 2 MSPS. Echo clock mode and ADC master clock mode relax the timing requirements and simplify the use of digital isolators.The 64-ball chip scale package ball grid array (CSP_BGA) of the AD4630-24 integrates all critical power supply and reference bypass capacitors, reducing the footprint and system component count, and lessening sensitivity to board layout.APPLICATIONS Automatic test equipment Digital control loops Medical instrumentation Seismology Semiconductor manufacturing Scientific instrumentation

The AD5160 provides a compact 2.9 mm ? 3 mm packaged solution for 256-position adjustment applications. These devices perform the same electronic adjustment function as mechanical potentiometers1 or variable resistors but with enhanced resolution, solid-state reliability, and superior low temperature coefficient performance.The wiper settings are controllable through an SPI-compatible digital interface. The resistance between the wiper and either end point of the fixed resistor varies linearly with respect to the digital code transferred into the RDAC latch.Operating from a 2.7 V to 5.5 V power supply and consuming less than 5 ?A allows for usage in portable battery-operated applications.

The AD5204/AD5206 provide 4-/6-channel, 256-position digitally controlled variable resistor (VR) devices. These devices perform the same electronic adjustment function as a potentiometer or variable resistor. Each channel of the AD5204/AD5206 contains a fixed resistor with a wiper contact that taps the fixed resistor value at a point determined by a digital code loaded into the SPI-compatible serial-input register. The resistance between the wiper and either endpoint of the fixed resistor varies linearly with respect to the digital code transferred into the VR latch. The variable resistor offers a completely programmable value of resistance between the A terminal and the wiper or the B terminal and the wiper. The fixed A-to-B terminal resistance of 10 k?, 50 k?, or 100 k? has a nominal temperature coefficient of 700 ppm/?C.Each VR has its own VR latch that holds its programmed resistance value. These VR latches are updated from an internal serial-to-parallel shift register that is loaded from a standard 3-wire serial-input digital interface. Eleven data bits make up the data-word clocked into the serial input register. The first three bits are decoded to determine which VR latch is loaded with the last eight bits of the data-word when the CS strobe is returned to logic high. A serial data output pin at the opposite end of the serial register (AD5204 only) allows simple daisy chaining in multiple VR applications without requiring additional external decoding logic.An optional reset (PR) pin forces all the AD5204 wipers to the midscale position by loading 0x80 into the VR latch.The AD5204/AD5206 are available in the 24-lead surface-mount SOIC and TSSOP packages. The AD5204 is also available in a 32-lead, 5 mm ? 5 mm LFCSP package. All parts are guaranteed to operate over the extended industrial temperature range of ?40?C to +85?C.
