AS1545 - SAR ADC

Description

The AS1545 is a dual, 12-bit, 6-channel, 1 MSPS, high speed, successive approximation (SAR) analog-todigital converters (ADCs).

The AS1545 is designed to operate with a single +2.7V to +5.25V supply and a sampling rate of up to 1 MSPS.

Features

  • flexible power-down modes to reduce power consumption at slower throughput rate. The AS1545 contains an internal 2.5V reference and integrated reference buffer that can be over driven when an external reference is required. Superior AC characteristics, low power consumption, and highly reliable packaging makes the AS1545 perfect for portable battery-powered remote sensors and dataacquisition devices. The AS1545 is available in a 32-lead TQFN package. 2 Key Features ! ! ! Sampling Rate: 1MSPS p.

Da t as heet AS1545 Dual, 12-Bit, 1MSPS, SAR ADC www.DataSheet4U.com 1 General Description The AS1545 is a dual, 12-bit, 6-channel, 1 MSPS, high speed, successive approximation (SAR) analog-todigital converters (ADCs). The AS1545 is designed to operate with a single +2.7V to +5.25V supply and a sampling rate of up to 1 MSPS. The device contains two ADCs, each preceded by a 6channel multiplexer and a high-bandwidth track/hold amplifier. Data access is made via standard control inputs in support of wide range of microprocessors and DSPs. The device requires very low supply-current at the 1MSPS maximum sampling speed, and features flexible power-down modes to reduce power consumption at slower throughput rate. The AS1545 contains an internal 2.
