Touchstone Semiconductor Announces The TSA7887 - A 12-bit, 125-ksps ADC

Touchstone Semiconductor TSA7887

The New TSA7887 Is $3 Less Expensive, Pin-Compatible, and Spec-Identical to AD7887

Touchstone Semiconductor announced the immediate availability of the TSA7887. The new TSA7887 is a two-channel, 12-bit, 125-ksps analog-to-digital converter (ADC) that can be used as a drop-in replacement for the Analog Devices AD7887.

Touchstone - TSA7887

Priced at $1.25 in 1,000-piece quantities, the new Touchstone TSA7887 is $3 less expensive, pin-compatible, specification-identical, and functionally identical to the Analog Devices’ AD7887. Touchstone now offers a total of 17 parts from Maxim and Analog Devices in its alternate-source analog IC family.

Touchstone’s alternate-source parts are drop-in replacements that can be used in conjunction with the original manufacturer’s ICs. All Touchstone alternate-source analog ICs are in stock and available to ship immediately.

The new TSA7887’s features include:

  • A $1.25 price at 1k-piece quantities -- $3 lower than the AD7887.
  • 2.6-mW power consumption at 125ksps while operating from a single +2.7V to +5.25V.
  • Four user-programmable, low-power operating modes including auto standby and auto power down.
  • -40°C to +125°C operating temperature.
  • One or two analog inputs each with an input range from 0V to VREF or 0V to VDD.
  • An integrated 2.5V reference.

The TSA7887 is an ideal choice as an easy-to-use 12-bit ADC in process control and data-acquisition applications. Some portable applications for the TSA7887 include: optical sensors, touch panels, personal digital assistants, programmable logic controllers, and medical instrumentation.

The TSA7887 is available in 8-pin SOIC and MSOP packages.
