AD10242
LAST TIME BUYDual Channel, 12-Bit, 40 MSPS MCM A/D Converter with DC-Coupled Analog Input Signal Conditioning (AD9042 Core ADC)
Part Details
- 2 Matched ADCs with Input Signal Conditioning
- Selectable Bipolar Input Voltage Range
(±0.5 V, ±1.0 V, ±2.0 V)
- Full MIL-STD-883B Compliant
- 80 dB Spurious-Free Dynamic Range
- Trimmed Channel-Channel Matching
The AD10242 is a complete dual signal chain solution including on-board amplifiers, references, ADCs, and output buffering providing unsurpassed total system performance. Each channel is laser trimmed for gain and offset matching and provides channel-to-channel crosstalk performance better than 80 dB. The AD10242 utilizes two each of the AD9631, OP279, and the AD9042 in a custom MCM to gain space, performance, and cost advantages over solutions previously available.
The AD10242 operates with ±5.0 V for the analog signal conditioning with a separate +5.0 V supply for the analog-to-digital conversion. Each channel is completely independent allowing operation with independent encode or analog inputs. The AD10242 also offers the user a choice of analog input signal ranges to minimize additional signal conditioning required for multiple functions within a single system. The heart of the AD10242 is the AD9042 which is designed specifically for applications requiring wide dynamic range.
The AD10242 is manufactured by Analog Devices on our MIL-PRF-38534 MCM line and is completely qualified. Units are packaged in a custom cofired ceramic 68-lead gull wing package and specified for operation from –55°C to +125°C. Contact the factory for additional custom options including those which allow the user to ac couple the ADC directly, by-passing the front end amplifier section. Also see the AD9042 data sheet for additional details on ADC performance.
