1 Temperature range for the B version is −40°C to +85°C. The AD7606 is operational up to 125°C with throughput rates ≤ 160 kSPS, and the SNR typically reduces by
0.7 dB at 125°C.
2 See the Terminology section.
3 This specification applies when reading during a conversion or after a conversion. If reading during a conversion in parallel mode with VDRIVE = 5 V, SNR typically reduces by 1.5 dB
and THD by 3 dB.
4 LSB means least significant bit. With ±5 V input range, 1 LSB = 152.58 µV. With ±10 V input range, 1 LSB = 305.175 µV.
5 These specifications include the full temperature range variation and contribution from the internal reference buffer but do not include the error contribution from
the external reference.
6 Bipolar zero code error is calculated with respect to the analog input voltage. See the Analog Input Clamp Protection section.
7 Sample tested during initial release to ensure compliance.
8 Operational power/current figure includes contribution when running in oversampling mode.
