NOTES
1
LSB means least significant bit. With a
±
10 V input, one LSB is 305
μ
V.
2
Typical rms noise at worst case transitions and temperatures.
3
Measured with fixed resistors as shown in Figure 5 (AD976) and Figure 6 (AD976A). Adjustable to zero as shown in Figure 7.
4
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.
5
f
= 45 kHz, 0.5 dB down, unless otherwise noted.
6
All specifications in dB are referred to a full scale
±
10 V input.
7
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.
8
Recovers to specified performance after a 2

input overvoltage.
