Original Press Release:
COTS Grade 12-Bit, 8-Channels, Low Power Analog-to-Digital Converter
Mansfield, MA – DATEL, Inc. has announced the introduction of the ADS-429 Series, a new line of multi-channel Analog-to-Digital converters that offer 12-bit resolution and are housed in a 16-pin plastic TSSOP package. Available in two low-cost, enhanced Commercial of the Shelf (COTS) grades it is the best choice for all military, airborne, and aerospace applications.
Each unit features no missing codes, ±0.5 LSB of Differential Non-Linearity, ±0.5 of Integral Non-Linearity and is 100% tested for performance across one of the two temperature ranges: –40 to +105ºC (ADS-429SE); –55 to +125ºC (ADS-429SM). The ADS-429 requires only one supply voltage for operation ranging from +2.7 to 5.25V and consumes only 3mA of supply current. It has a sleep mode feature that consumes only 8uA of current. It is the ideal selection for low power and battery operated multi-channel Data Acquisition Systems.
The ADS-429 offers a unique architecture that includes a sample-hold, a successive approximation A/D, and an SPI compatible serial interface. It features an excellent signal-to noise ratio (SNR) of 73dB and a total harmonic distortion (THD) of -85dB, which makes the ADS-429 the ideal choice for both time domain (imaging, telemetry, process control) and frequency-domain (radar, telecommunications, spectrum analysis) applications.
For the more demanding and ruggedized application, DATEL also offers this family of products as fully screened high reliability ADS-429–QL and ADS-429/883 models. These two MIL-STD models are offered in a hermetically sealed ceramic package to protect the IC from the effects of moisture/outgassing and to isolate the IC from the stresses that may occur on the printed circuit. Please contact DATEL for pricing and detailed information on these models. Samples for both ADS-429SE and ADS-429SM are available upon request. Burn-in, lot and ATE traceability are also offered.
