Overview
The AD5570BRSZ-REEL, produced by Analog Devices Inc., is a single 16-bit serial input, voltage output Digital-to-Analog Converter (DAC). This device operates from supply voltages of ±11.4 V up to ±16.5 V, making it versatile for various applications. The AD5570 features high accuracy with integral linearity (INL) and differential nonlinearity (DNL) accurate to 1 LSB. It is designed to ensure the DAC output is clamped to 0 V during power-up, and it includes a power-down pin to reduce current consumption to 16 μA in low power states. The device is available in a 16-lead SSOP package and supports a wide temperature range of −40°C to +125°C for certain versions.
