NOTES
1LSB means least significant bit. With a
± 10 V input, one LSB is 305 V.
2Typical rms noise at worst case transitions and temperatures.
3Measured with fixed resistors as shown in Figure 5 (AD976) and Figure 6 (AD976A). Adjustable to zero as shown in Figure 7.
4Full-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.
5f
IN = 20 kHz (AD976) and fIN = 45 kHz (AD976A), 0.5 dB down, unless otherwise noted.
6All specifications in dB are referred to a full scale
± 10 V input.
7Full-power bandwidth is defined as full-scale input frequency at which signal-to-(noise + distortion) degrades to 60 dB or 10 bits of accuracy.
8Recovers to specified performance after a 2
× F
S input overvoltage.
Specifications subject to change without notice.
(–40 C to +85 C, FS = 100 kHz, Ref = Internal Reference,
VDIG = VANA = +5 V unless otherwise noted)
