AD9203 10位、40 MSPS、低功耗模数转换器

AD9203: 10位、40 MSPS、低功耗模数转换器

AD9203是一款单芯片、10位、40 MSPS模数转换器(ADC)，采用单电源供电，内置一个片内基准电压源。它采用多级差分流水线架构，数据速率达40 MSPS，在整个工作温度范围内保证无失码。输入范围可在1 V p-p至2 V p-p之间进行调整。该ADC具有一个片上可编程基准电压源。也可以选用外部基准电压源，以满足应用的直流精度与温度漂移要求。当以较低的采样速率工作时，可以使用一个外部电阻来降低功耗。采用一个单时钟输入来控制所有内部转换周期。数字输出数据格式为标准二进制或二进制补码。超量程(OTR)信号表示溢出状况，可由最高有效位来确定是下溢还是上溢。AD9203采用2.7 V至3.6 V电源供电，非常适合高速便携式应用中的低功耗操作。AD9203采用先进的CMOS工艺制造，提供28引脚超薄紧缩小型封装(28 TSSOP)，额定温度范围为-40°C至+85°C工业温度范围。

The AD9203 is a monolithic low power, single supply, 10-bit, 40 MSPS analog-to-digital converter with an on-chip voltage reference. It uses a multistage differential pipeline architecture at 40 MSPS data rate and guarantees no missing codes over the full operating temperature range. Its input range may be adjusted between 1 V and 2 V p-p.

The ADC has an on-board programmable reference. An external reference can also be chosen to suit the DC accuracy and temperature drift requirements of an application. An external resistor can be used to reduce power consumption when operating at lower sampling rates.

A single clock input is used to control all internal conversion cycles. The digital output data is presented in straight binary or two's complement output format. An out-of-range signal (OTR) indicates an over-flow condition that can be used with the most significant bit to determine over-flow or under-flow. The AD9203 can operate with a supply range from 2.7 V to 3.6 V, attractive for low power operation in high-speed portable applications.Fabricated on an advanced CMOS process, the AD9203 is available in a 28-pin thin shrink small outline package (28 TSSOP) specified over the industrial temperature range (-40°C to +85°C).
