ADS8557IPMR Texas Instruments Analog-to-Digital Converter

The ADS8557IPMR from Texas Instruments is a 14-bit, 6-channel, simultaneous sampling analog-to-digital converter (ADC). It is a successive approximation register (SAR) ADC that operates at a maximum sampling rate of 670 kSPS. The ADS8557IPMR can accept single-ended or differential input signals in the range of ±12 V. It has a built-in 2.5 V or 3 V reference, but an external reference can also be used.

The ADS8557IPMR has a number of features that make it well-suited for a wide range of applications, including:

• Simultaneous sampling: The ADS8557IPMR can sample all six of its channels simultaneously, which is ideal for applications where it is important to preserve the phase information of the input signals.
• High speed: The ADS8557IPMR has a maximum sampling rate of 670 kSPS, which makes it suitable for applications where high-speed data acquisition is required.
• Wide input range: The ADS8557IPMR can accept input signals in the range of ±12 V, which makes it suitable for a wide range of applications.
• Low power consumption: The ADS8557IPMR consumes very little power, making it ideal for battery-powered applications.

The ADS8557IPMR is available in a 64-pin LQFP package. It is RoHS compliant and has a moisture sensitivity level (MSL) of 3.
