AD7440规格书详情
GENERAL DESCRIPTION
The AD7440/AD7450A1 are 10-bit and 12-bit high speed, low
power, successive approximation (SAR) analog-to-digital
converters with a fully differential analog input. These parts
operate from a single 3 V or 5 V power supply and use
advanced design techniques to achieve very low power
dissipation at throughput rates up to 1 MSPS. The SAR
architecture of these parts ensures that there are no pipeline
delays.
The parts contain a low noise, wide bandwidth, differential
track-and-hold amplifier (T/H) that can handle input
frequencies up to 3.5 MHz. The reference voltage is applied
externally to the VREF pin and can be varied from 100 mV to
3.5 V depending on the power supply and what suits the
application. The value of the reference voltage determines the
common-mode voltage range of the part. With this truly
differential input structure and variable reference input, the
user can select a variety of input ranges and bias points.
The conversion process and data acquisition are controlled
using CS and the serial clock, allowing the device to interface
with microprocessors or DSPs. The input signals are sampled
on the falling edge of CS; the conversion is also initiated at this
point. The SAR architecture of these parts ensures that there are
no pipeline delays. The AD7440 and the AD7450A use advanced
design techniques to achieve very low power dissipation at high
throughput rates.

AD7440属于集成电路(IC) > 模数转换器(ADC)。亚德诺半导体技术有限公司制造生产的AD7440模数转换器(ADC)模数转换器(ADC、A/D 或 A 转 D)对模拟信号进行采样,例如由麦克风采集的声音或传感器的输出,然后将其转换为数字信号。一般来说,数字输出是二进制补码二进制数,与输入成比例。输入类型可能是差分、伪差分或单端输入。模数转换器可按照位数、采样率、输入数、接口、转换器数和架构(例如自适应增量、双斜率、折叠、流水线、SAR、三角积分、两步式)进行选择。
