16-Bit 100 kSPS Oversampling ADC AD776
●PRODUCT DESCRIPTION
■The AD776 is a 16-bit sigma-delta oversampled ADC, incorporating a 1-bit third-order modulator and digital decimation filter. An on-cKip voltage reference circuit is also included.
■The AD776 does not generally require the use of sample-hold circuits or complex antialiasing filters as a result of its sigmadelta architecture. The output is available both before and after the final Finite Impulse Response (FIR) decimation filter. This provides the flexibility of optimizing conversion speed or dynamic range: 12-bit/400 kHz (from the comb filter) or 16-bit/ 100 kHz (from the FIR filter). The serial port provides easy interface with a variety of standard processors including the ADSP-21XX.
■The AD776 is specified for ac (or“dynamic”）parameters such as SNR, THD and IMD which are important in signal processing and audio applications. Third order noise shaping is employed using 64 times oversampling to provide 90 dB SNR and —100 dB peak spurious component for signal band widths up to 45 kHz.
■The AD776 operates from a single +5 V supply and typically consumes 350 mW during conversion. The device is packaged in 20-pin ceramic DIP (cerdip) and is offered in an industrial temperature grade(~40°C to -85°C).
