¹Operating temperature range is as follows: –40°C to +85°C. Therefore, T_MIN= –40°C and T_MAX= +85°C.

²Test conditions: Input PGA set for 0 dB gain, Output PGA set for 6 dB gain, no load on analog outputs (unless otherwise stated).

³At input to sigma-delta modulator of ADC.

⁴Guaranteed by design.

⁵Overall group delay will be affected by the sample rate and the external digital filtering.

⁶The ADC’s input impedance is inversely proportional to DMCLK and is approximated by: (4 × 10¹¹)/DMCLK.

⁷Between VOUTP and VOUTN.

⁸At VOUT output.

⁹Frequency responses of ADC and DAC measured with input at audio reference level (the input level that produces an output level of –10 dBm0), with 38 dB preamplifier

bypassed and input gain of 0 dB.

¹⁰Test conditions: no load on digital inputs, analog inputs ac coupled to ground, no load on analog outputs.

Specifications subject to change without notice.
