Linear Technology LTC1861L
The LTC1861L offers a softwareselectable 2-channel MUX and an external reference pin on the MSOP version. The 3-wire, serial I/O, MSOP or SO-8 package and extremely high sample rate-to-power ratio make these ADCs ideal choices for compact, low power, high speed systems. These ADCs can be used in ratiometric applications or with external references.| Part No. | LTC1861L |

At 150ksps, the supply current is only 450µA. The supply current drops at lower speeds because the LTC1860L/LTC1861L automatically power down between conversions. These 12-bit switched capacitor successive approximation ADCs include sample-and-holds. The LTC1860L has a differential analog input with an external reference pin.
