Wolfson Microelectronics plc WM2630
The WM2630 is an octal, 12-bit, resistor string digital-toanalogue converter. The eight individual DACs contained in the IC can be switched in pairs between fast and slow (low power) operation modes, or powered down, under software control. The DAC outputs are buffered by a rail-to-rail amplifier with a gain of two, which is configurable as Class A (fast mode) or Class AB (for low-power mode).| Part No. | WM2630 |

DESCRIPTION
Alternatively, the whole device can be powered down, reducing current consumption to less than 0.1µ A. The WM2630 has been designed to interface directly to industry standard microprocessors and DSPs, and can operate on two separate analogue and digital power supplies. It is programmed with a 16-bit serial word comprising 4 address bits and up to 12 DAC or control register data bits. All eight DACs can be simultaneously forced to a preset value using a preset input pin. A daisy-chain data output makes it possible to control several of Wolfson’s octal DACs from the same interface, without increasing the number of control lines.
