AD87610-Bit 20 MSPS 160 mW CMOS A/D Converter | Analog to Digital Converters (ADC) | 3 | Active | The AD876 is a CMOS, 160 mW, 10-bit, 20 MSPS analog-to-digital converter (ADC). The AD876 has an on-chip input sample-and-hold amplifier. By implementing a multistage pipelined architecture with output error correction logic, the AD876 offers accurate performance and guarantees no missing codes over the full operating temperature range. Force and sense connections to the reference inputs minimize external voltage drops.The AD876 can be placed into a stand-by mode of operation reducing the power below 50 mW. The AD876’s digital I/O interfaces to either +5 V or +3.3 V logic. Digital output pins can be placed in a high impedance state; the format of the output is straight binary coding.The AD876's speed, resolution and single-supply operation ideally suit a variety of applications in video, multimedia, imaging, high speed data acquisition and communications. The AD876's low power and single-supply operation satisfy requirements for high speed portable applications. Its speed and resolution ideally suit charge coupled device (CCD) input systems such as color scanners, digital copiers, electronic still cameras and camcorders.The AD876 comes in a space saving 28-pin SOIC and 48-pin thin quad flatpack (TQFP) and is specified over the commercial (0°C to +70°C) temperature range.PRODUCT HIGHLIGHTSLow PowerThe AD876 at 160 mW consumes a fraction of the power of presently available 8- or 10-bit, video speed converters. Powerdown mode and single-supply operation further enhance its desirability in low power, battery operated applications such as electronic still cameras, camcorders and communication systems.Very Small PackageThe AD876 comes in a 28-lead SOIC, 28-lead SSOP, and 48- lead surface mount, thin quad flat package.

AD8801Octal 8-Bit TrimDAC with Power Shutdown & Mid-Scale Preset | Data Acquisition | 2 | Obsolete | The AD8801 /AD8803provides eight digitally controlled dc voltage outputs. This potentiometer divider TrimDAC®allows replacement of the mechanical trimmer function in new designs. The AD8801 / AD8803 is ideal for dc voltage adjustment applications.Easily programmed by serial interfaced microcontroller ports, the AD8801 with its midscale preset is ideal for potentiometer replacement where adjustments start at a nominal value. Applications such as gain control of video amplifiers, voltage controlled frequencies and bandwidths in video equipment, geometric correction and automatic adjustment in CRT computer graphic displays are a few of the many applications ideally suited for these parts. The AD8803 provides independent control of both the top and bottom end of the potentiometer divider allowing a separate zero-scale voltage setting determined by the VREFLpin. This is helpful for maximizing the resolution of devices with a limited allowable voltage control range.Internally the AD8801 / AD8803 contain eight voltage output digital-to-analog converters, sharing a common reference voltage input.Each DAC has its own DAC register that holds its output state. These DAC registers are updated from an internal serial-to-parallel shift register that is loaded from a standard three-wire serial input digital interface. Eleven data bits make up the data word clocked into the serial input register. This data word is decoded where the first 3 bits determine the address of the DAC register to be loaded with the last 8 bits of data. The AD8801 / AD8803 consumes only 5 mA from 5 V power supplies. In addition, in shutdown mode reference input current consumption is also reduced to 5 µA while saving the DAC latch settings for use after return to normal operation.The AD8801 / AD8803 is available in 16-pin plastic DIP and the 1.5 mm height SO-16 surface mount packages. |
