14-bit A/D converter guaranteed for high-temperature apps

Milpitas, Calif.—Linear Technology has introduced the LTC2246H, a 25-Msps, 14-bit A/D converter for high temperature, high reliability data acquisition systems.

The LTC2246H, guaranteed for operation across the -40°C to 125°C temperature range, satisfies the high temperature demands of automotive and military applications. Additionally, the LTC2246H is offered in a leaded package, allowing for easier inspection of solder joints in manufacturing. This high speed A/D converter is targeted for collision avoidance radar (CAR) automotive systems.

At 14 bits, 25Msps, the LTC2246H consumes 75-mW, and provides 74.5-dB signal to noise ratio (SNR) and 90dBc spurious free dynamic range (SFDR) baseband performance.

The LTC2246H is packaged in a small 5mm x 5mm TQFP package with integrated bypass capacitors, requiring only a small number of external components for more compact, cost effective designs.

For lower-resolution requirements, Linear Technology is also offering the pin-compatible 12-bit 25Msps LTC2226H.

Pricing: The H-grade (-40°C to 125°C) LTC2226H and LTC2246H is $10.80 and $18.00, respectively, each in 1,000-piece quantities.
Availability: Now.
Datasheet: LTC2226H and LTC2246H.
