Touchstone adds to Maxim ADC replacements

Touchstone Semiconductor announced availability of 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, according to the company. It is also claimed to be 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.

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.

The TSM1285 addresses applications such as 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.

Touchstone offers free samples and completely assembled/tested demo boards.
