Touchstone Semiconductor Second Sources Maxim A/D Converter

Touchstone Semiconductor announced the immediate availability of the TSM1285, a new 12-bit, 300ksps 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.
