Specifications subject to change without notice.
LSB means least significant bit. With a 10 V input, one LSB is 305 V.
Typical rms noise at worst case transitions and temperatures.
Measured with fixed resistors as shown in Figure 5 (AD976) and Figure 6 (AD976A). Adjustable to zero as shown in Figure 7.
Full-scale error is expressed as the % difference between the actual full-scale code transition voltage and the ideal full-scale transition voltage and includes the effect
of offset error. The full-scale error is the worst case of either the –full-scale or +full-scale code transition voltage errors.
f
All specifications in dB are referred to a full scale 10 V input.
Full-power bandwidth is defined as full-scale input frequency at which signal-to-(noise + distortion) degrades to 60 dB or 10 bits of accuracy.
