AD7938BSUZ-6

AD7938-6 is a 12bit, high speed, low power, successive approximation (SAR) analogue-to-digital converter (ADC). The part contains a low noise, wide bandwidth, differential track-and-hold amplifier that can handle input frequencies up to 50MHz. The AD7938-6 features eight analogue input channels with a channel sequencer that allows a preprogrammed selection of channels to be converted sequentially. The part can operate with either single-ended, fully differential, or pseudo differential analogue inputs. The AD7938-6 uses advanced design techniques to achieve very low power dissipation at high throughput rates. The part also features flexible power management options. An on-chip control register allows the user to set up different operating conditions, including analogue input range and configuration, output coding, power management, and channel sequencing.
