PCM1750

SPECIFICATIONS

ELECTRICAL

At 25

°C, and ±V

A = ±5.0V; +VD = +5.0V, unless otherwise noted. Where relevant, specifications apply to both left and right input/output channels.

NOTES: (1) Binary Two’s Complement coding. (2) The PCM1750 is tested and guaranteed at 5.2

µs, however it will operate at 4.5µs. The dynamic performance is not

guaranteed or tested at this conversion rate. (3) Ratio of SignalRMS / (DistortionRMS + NoiseRMS). (4) A/D converter sample frequency (4 x 48kHz; 4X oversampling per

channel). (5) A/D converter input frequency (signal level). (6) Referred to input signal level. (7) Ratio of (DistortionRMS + NoiseRMS) / SignalRMS. (8) Externally adjustable

to zero error. (9) Differential non-linearity error at bipolar major carry input code. Externally adjustable to zero error. (10) Full scale range (5.50V). (11) Refer to equivalent

circuit in Figure 1. (12) Worst case operating condition. Refer to typical performance curves.
