MAX1291

250ksps, 3V, 8-/4-Channel, 12-Bit ADCs with 2.5V Reference and Parallel Interface

General Description The MAX1291/MAX1293 low-power, 12-bit analog-to-digital converters (ADCs) feature a successive-approximation ADC, automatic power-down, fast wake-up (2µs), an on-chip clock, +2.5V internal reference, and a high speed, byte-wide parallel interface. They operate with a single +3

MAX1291

250ksps、+3V、8/4通道、12位ADC,带有+2.5V电压基准及并行接口

MAX1291/MAX1293低功耗、12位模数转换器(ADC)是一款逐次逼近型ADC,具有自动关断、快速唤醒(2µs)功能,提供片内时钟、+2.5V内部基准电压源,以及一个高速、字节宽并行接口。它们采用+3V模拟单电源供电,并通过一个VLOGIC引脚直接与+1.8V至+5.5V数字电源进行接口。\n\n 在250ksps的最大采样速率下功耗仅为5.7mW (VDD = VLOGIC)。MAX1291/MAX1293具有两种软件可选的关断模式,因此可在两次转换之间关断;访问并行接口即可使其恢复正常工作。通过在两次转换之间关断,可以在采样速率降低的情况下将电源电流降至10µA以下。 \ • 12位分辨率,±0.5 LSB线性度\n\n• +3V单电源供电\n\n• 用户可调逻辑电平(+1.8V至+3.6V)\n\n• +2.5V内部基准电压源\n\n• 软件可配置的模拟输入多路复用器\n• 8通道单端/4通道伪差分(MAX1291)\n\n• 4通道单端/2通道伪差分(MAX1293)\n\n\n\n\n• 软件可配置的单极性/双极性输入\n\n• 低功耗:\n• 1.9mA (250ksps)\n\n• 1.0mA (100ksps)\n\n• 400µA (10ksps)\n\n• 2µA(关断)\n\n\n\n\n• 内部3MHz全功率带宽采样/保持\n\n• 字节宽并;
