NATIONAL SEMICONDUCTOR ADC161S626 Manual
The ADC161S626 is a 16-bit successive-approximation register (SAR) Analog-to-Digital converter (ADC) with a maximum sampling rate of 250 kSPS. The ADC161S626 has a minimum signal span accuracy of ± 0.003% over the temperature range of −40°C to +85°C. The converter features a differential analog input with an excellent common-mode signal rejection ratio of 85 dB, making the ADC161S626 suitable for noisy environments. The ADC161S626 operates with a single analog supply (VA) and a separate digital input/output (VIO) supply. VA can range from +4.5V to +5.5V and VIO can range from +2.7V to +5.5V. This allows a system designer to maximize performance and minimize power consumption by operating the analog portion of the ADC at a VA of +5V while interfacing with a +3.3V controller. The serial data output is binary 2's complement and is SPI™ compatible. The performance of the ADC161S626 is guaranteed over temperature at clock rates of 1 MHz to 5 MHz and reference voltages of +2.5V to +5.5V. The ADC161S626 is available in a small 10-lead MSOP package. The high accuracy, differential input, low power consumption, and small size make the ADC161S626 ideal for direct connection to bridge sensors and transducers in battery operated systems or remote data acquisition applications.

NATIONAL SEMICONDUCTOR LM3691 High Accuracy Miniature 1A Step-Down DC-DC Converter for Portable Applications handbook
LM3691 is a high-accuracy, miniature, 1A step-down DC-DC converter from TI that is optimized for powering ultra-low voltage circuits from a single Li-Ion cell or three cell NiMH/NiCd batteries. It provides up to 1A load current over an input voltage range from 2.3V to 5.5V. There are several different fixed voltage output options available. LM3691 has a mode-control pin that allows the user to select Forced PWM mode or ECO mode that changes modes between gated PWM mode and PWM automatically depending on the load. In ECO mode, LM3691 offers superior efficiency and very low Iq under light load conditions. ECO mode extends the battery life through reduction of the quiescent current during light load conditions and system standby. LM3691 is available in a 6-bump micro SMD package. Only three external surface-mount components are required: a 1μH inductor, a 4.7μF input capacitor and a 4.7μF output capacitor.
