Interview with Mr. Apoorva Awasthy of TI on new low power ADC driver ICs from TI

Texas Instruments (TI) makes few finest amplifiers for instrumentation and medical applications. TI has recently released a new family of differential amplifiers called TSH452X series. Mr. Apoorva Awasthy, Business Development Manager, High Performance Analog, Texas Instruments India, has shared his views on this product family as well as on precision analog semiconductor industry.

Question: What are the applications the TSH452X family is most suitable for? Is this suitable for medical electronics applications like ECG and EEG?

Mr. Awasthy: The TSH452X is targeted at applications across verticals like audio, industrial and medical. The device also finds application in battery-operated devices and other applications with sensitive power budgets, for example, pressure measurement flow meters, ECG and EEG machines, etc. The devices in this family draw a quiescent current of only 1.14 milliamps at a bandwidth of 145 MHz, thereby giving design engineers the flexibility to work on designs where power is a constraint. .

As most of the ECG and EEG machines are becoming portable, the TSH452X family of amplifiers is well suited for these end equipments. These devices enable precision delta sigma and SAR analog-to-digital converters to digitize inputs from sensors and other real world analog input signals while consuming ...
