NXP Semiconductors Product specification
Low-cost stereo filter DAC UDA1330ATS
Notes
1. All supply connections must be made to the same external power supply unit.
2. The digital input pads are TTL compatible at 5 V, but the pads are not 5 V tolerant in the voltage range between
2.7 and 4.5 V.
3. When the DAC drives a capacitive load above 50 pF, a series resistance of 100 Ω must be used to prevent
oscillations in the output operational amplifier.
