General Description
AD7475 General Description
The AD7475/AD7495 are 12-bit high-speed, low-power,successive-approximation ADCs. The parts operate from a single 2.7 V to 5.25 V power supply and feature throughput rates up to 1 MSPS. The parts contain a low-noise, wide bandwidth track/hold amplifier that can handle input frequencies in excess of 1 MHz.
The conversion process and data acquisition are controlled using CS and the serial clock allowing the devices to interface with microprocessors or DSPs. The input signal is sampled on the falling edge of CS and conversion is also initiated at this point.There are no pipelined delays associated with the part.
The AD7475/AD7495 use advanced design techniques to achieve very low power dissipation at high throughput rates. With 3 V supplies and 1 MSPS throughput rate, the AD7475 consumes just 1.5 mA, while the AD7495 consumes 2 mA. With 5 V supplies and 1 MSPS, the current consumption is 2.1 mA for the AD7475 and 2.6 mA for the AD7495.
The analog input range for the part is 0 V to REF IN. The 2.5 V reference for the AD7475 is applied externally to the REF IN pin while the AD7495 has an on-board 2.5 V reference. The conversion time is determined by the SCLK frequency.

NOTES
1 Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
2 Transient currents of up to 100 mA will not cause SCR latch-up.
