ADS7843IDBQRQ1 Description

Short technical summary and product information.

The ADS7843IDBQRQ1 from Texas Instruments is a 12-bit sampling Analog-to-Digital Converter (ADC) designed for driving touch screens. It features a synchronous serial interface and low on-resistance switches, making it suitable for battery-operated systems.

 

This controller supports programmable 8- or 12-bit resolution and operates with a single supply voltage ranging from 2.7V to 5V. It offers a conversion rate of up to 125kHz and includes 2 auxiliary analog inputs. The device has a typical power dissipation of 750μW at 125kHz and a +2.7V supply, with a shutdown mode reducing power consumption to under 0.5μW.

 

The ADS7843IDBQRQ1 is qualified for automotive applications and operates within a temperature range of -40°C to 125°C. It is supplied in an SSOP-16 package, designed for surface mounting.

 

This part is currently in the process of being discontinued. New designs should consider an alternate product such as the TSC2013-Q1.
