The MAX1436B is a low-power, high-performance analog-to-digital converter (ADC) from TI that features fully differential inputs, a pipelined architecture, and digital error correction incorporating a fully differential signal path. This ADC is optimized for low-power and high-dynamic performance in medical imaging instrumentation and digital communications applications. The MAX1436B operates from a 1.8V sin- gle supply and consumes only 743mW (93mW per channel) while delivering a 69.9dB (typ) signal-to-noise ratio (SNR) at a 5.3MHz input frequency. In addition to low operating power, the MAX1436B features a low- power standby mode for idle periods. An internal 1.24V precision bandgap reference sets the full-scale range of the ADC. A flexible reference struc- ture allows the use of an external reference for applica- tions requiring increased accuracy or a different input voltage range. The reference architecture is optimized for low noise. A single-ended clock controls the data-conversion process. An internal duty-cycle equalizer compensates for wide variations in clock duty cycle. An on-chip PLL generates the high-speed serial low-voltage differential signal (LVDS) clock. The MAX1436B has self-aligned serial LVDS outputs for data, clock, and frame-alignment signals. The output data is presented in two’s complement or binary format. The MAX1436B offers a maximum sample rate of 40Msps. See the Pin-Compatible Versions table below for higher-speed versions.

The MAX1436B is an octal, 12‑bit analog‑to‑digital converter optimized for low‑power, high‑dynamic‑range applications such as medical imaging and multichannel communications. It operates from a 1.8 V supply, consumes 743 mW total (93 mW per channel) and delivers up to 69.9 dB SNR at a 5.3 MHz input frequency. The device includes fully differential inputs, an internal 1.24 V band‑gap reference, and serial LVDS outputs selectable for LVDS or SLVS mode.
The ADC is offered in a 100‑pin TQFP‑EP package (14 mm × 14 mm × 1 mm) qualified for an extended industrial temperature range (‑40 °C to +85 °C). Ordering information, absolute maximum ratings, electrical and timing characteristics, and package thermal data are provided in the datasheet.
