Overview
The MAX1135BEAP+T is a 16-bit, 150ksps analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This serially interfaced ADC is designed to connect directly to SPI, QSPI, and MICROWIRE devices without the need for external logic. It features a single 3.3V supply and is packaged in a 20-pin SSOP (Shrink Small Outline Package).
The MAX1135BEAP+T combines an input scaling network, internal track/hold (T/H), clock, and three general-purpose digital output pins for controlling external multiplexers or programmable gain amplifiers (PGAs). It is known for its excellent dynamic performance, high speed, and low power consumption, making it suitable for various applications including industrial process control, instrumentation, and medical devices.
