Description

The AD8303 is a complete (includes internal reference) dual,12-bit, voltage output digital-to-analog converter designed to operate from a single +3 volt supply. Built using a CBCMOSprocess, this monolithic DAC offers the user low cost and ease of-use in single-supply +3 volt systems. Operation is guaranteed over the supply voltage range of +2.7 V to +5.5 V making this device ideal for battery operated applications.The 2.0475 V full-scale voltage output is laser-trimmed to maintain accuracy over the operating temperature range of the device. The binary input data format provides an easy-to-use  one-half millivolt-per-bit software programmability. The voltage outputs are capable of sourcing 3 mA.

Part Number: ISL26104

Function: Low-Noise 24-bit Delta Sigma ADC

Package: TSSOP 28 Pin Type

Manufacturer: Intersil

Pinouts:

Description

The ISL26102 and ISL26104 provide a low-noise programmable gain amplifier along with a 24-bit Delta-Sigma Analog-to-Digital Converter with two channel (ISL26102) or four channel (ISL26104) differential, multiplexed inputs. The devices feature exceptional noise performance for conversion rates ranging from 2.5Sps to 4kSps.

The on-chip low-noise programmable-gain amplifier provides gains ranging from 1 to 128, which supports ±19.5mVFS from a 5V reference. The high input impedance allows direct connection of sensors such as load cell bridges to ensure the specified measurement accuracy without additional circuitry.
