Definitions of specified parameters

TSA1204

SINAD2Ao=6.02 × ENOB + 1.76 dB + 20 log (2A0/FS)

The ENOB is expressed in bits.

Analog input bandwidth

The maximum analog input frequency at which the spectral response of a full power signal

is reduced by 3 dB. Higher values can be achieved with smaller input levels.

Effective resolution bandwidth (ERB)

The band of input signal frequencies that the ADC is intended to convert without loosing

linearity i.e. the maximum analog input frequency at which the SINAD is decreased by 3 dB

or the ENOB by 1/2 bit.

Pipeline delay

Delay between the initial sample of the analog input and the availability of the corresponding

digital data output, on the output bus. Also called data latency. It is expressed as a number

of clock cycles.
