The speed, resolution, and single-supply operation are suited for applications in video, multimedia, imaging, high-speed acquisition, and commu- nications. The low-power and single-supply operation satisfy requirements for high-speed portable applications. The speed and resolution ideally suit charge-coupled device (CCD) input systems such as color scanners, digital copiers, electronic still cameras, and camcorders. A multistage pipelined architecture with output error correction logic provides for no missing codes over the full operating temperature range. Force and sense connections to the reference inputs provide a more accurate internal reference voltage to the reference resistor string. A standby mode of operation reduces the power to typically 15 mW. The digital I/O interfaces to either 5-V or 3.3-V logic and the digital output terminals can be placed in a high-impedance state. The format of the output data is straight binary coding. A pipelined multistaged architecture achieves a high sample rate with low power consumption. The TLC876 distributes the conversion over several smaller ADC sub-blocks, refining the conversion with progressively higher accuracy as the device passes the results from stage to stage. This distributed conversion requires a small fraction of the 1023 comparators used in a traditional flash ADC. A sample-and-hold amplifier (SHA) within each of the stages permits the first stage to operate on a new input sample while the second through the fifth stages operate on the four preceding samples. The TLC876C is characterized for operation from 0 °C to 70°C, the TLC876I is characterized for operation from –40 °C to 85°C, and the TLC876M is characterized for operation over the full military temperature range of –55°C to 125 °C.
