AD7416ARZ Overview
The AD7418 are 10-bit, 4-channel and single-channelADCs with an on-chip temperature sensor that can operate from asingle 2.7 V to 5.5 V power supply. The devices contain a 15 μssuccessive approximation converter, a 5-channel multiplexer, atemperature sensor, a clock oscillator, a track-and-hold, and areference (2.5 V). The AD7416 is a temperature-monitoring onlydevice in an 8-lead package.
The temperature sensor on the parts can be accessed via multiplexerChannel 0. When Channel 0 is selected and a conversionis initiated, the resulting ADC code at the end of the conversiongives a measurement of the ambient temperature (±1°C @ 25°C).On-chip registers can be programmed with high and low temperaturelimits, and an open-drain overtemperature indicator (OTI)output is provided, which becomes active when a programmedlimit is exceeded.
A configuration register allows programming of the sense of theOTI output (active high or active low) and its operating mode(comparator or interrupt). A programmable fault queue counterallows the number of out-of-limit measurements that mustoccur before triggering the OTI output to be set to preventspurious triggering of the OTI output in noisy environments.
An I2C compatible serial interface allows the AD7416/AD7417/AD7418 registers to be written to and read back. The threeLSBs of the AD7416/AD7417 serial bus address can be selected,which allows up to eight AD7416/AD7417 devices to be connectedto a single bus.
The AD7417 is available in a narrow body, 0.15 inch, 16-lead,small outline package (SOIC) and in a 16-lead, thin shrink,small outline package (TSSOP). The AD7416 and AD7418 areavailable in 8-lead SOIC and MSOP packages.
Product Highlights
- The AD7416/AD7417/AD7418 have an on-chip temperaturesensor that allows an accurate measurement of the ambienttemperature (±1°C @ 25°C, ±2°C overtemperature) to bemade. The measurable temperature range is 40°C to+125°C. An overtemperature indicator is implemented bycarrying out a digital comparison of the ADC code forChannel 0 (temperature sensor) with the contents of theon-chip TOTI setpoint register.
- The AD7417 offers a space-saving, 10-bit analog-to-digitalsolution with four external voltage input channels, an onchiptemperature sensor, an on-chip reference, and a clockoscillator.
- The automatic power-down feature enables the AD7416/AD7417/AD7418 to achieve superior power performance.At slower throughput rates, the part can be programmed tooperate in a low power shutdown mode, allowing furthersavings in power consumption.
