Touchstone adds new Maxim analog-to-digital converter to alternate-source product family

USA: Touchstone Semiconductor announced the immediate availability of the TSM1285, a new 12-bit, 300ksps analog-to-digital converter (ADC) that can be used as a drop-in replacement for Maxim’s MAX1285 ADC.

At $1.20 in 1000-piece quantities, the new Touchstone TSM1285 is five times less expensive, pin-compatible, function/specification-identical to Maxim Integrated Products’ MAX1285. It is also a four times higher-speed, pin-for-pin upgrade to the MAX1240 and MAX1241 ADCs at five times and four times lower price, respectively. Touchstone now offers 16 Maxim analog ICs as part of its alternate-source product family.

Touchstone’s alternate-source parts are drop-in replacements that can be used in conjunction with the original manufacturer’s ICs. Replacement parts ensure customers have access to a reliable supply of parts to build their products. All Touchstone alternate-source analog ICs are in stock and available to ship immediately.

The TSM1285’s features include:
* $1.20 price at 1k-piece quantities - five times lower than the MAX1285.
* High-bandwidth input track-and-hold and an integrated +2.5V reference.
* Low conversion-mode power consumption of 9mW at 300ksps from a single +2.7V to+3.6V.
* Easy-to-use, high-speed three-wire serial interface that connects directly to any microcontroller or other interface-compatible computing device without the need for separate, external logic.

The TSM1285 is suitable for PCB-space-conscious, low-power, remote-sensor and data-acquisition applications because of its low power, ease of use and small package footprint. Applications include process control and factory automation, data and low-frequency signal acquisition, portable data logging, pen digitizers and tablet computers, medical instrumentation and battery-powered instruments.

The TSM1285 is available in an 8-pin SOIC package. The TSM1285BC is fully specified over the 0°C to +70°C temperature range while the TSM1285BE is fully specified over the -40°C to +85°C temperature range.
