AD10242TZ

Overview

The AD10242TZ is a dual-channel, 12-bit, 40 MSPS mixed-signal module (MCM) featuring integrated analog input signal conditioning. It combines two AD9632 amplifiers, two OP279 buffers, and two AD9042 ADCs within a single custom cofired ceramic package. The device operates with ±5.0 V supplies for analog conditioning and a separate +5.0 V supply for digital conversion. Key electrical parameters include a guaranteed sample rate of 40 MSPS, an Spurious-Free Dynamic Range (SFDR) of 80 dB at –1 dBFS, and channel-to-channel crosstalk better than 80 dB. Each channel is laser-trimmed for gain and offset matching.

Feature Summary

• Dual 12-bit ADCs with integrated signal conditioning in a 68-lead ceramic leaded chip carrier
• Selectable bipolar input voltage ranges: ±0.5 V, ±1.0 V, or ±2.0 V
• Laser-trimed channels ensuring gain/offset matching and >80 dB inter-channel isolation
• Full MIL-STD-883B compliance with operation from –55°C to +125°C

Applications

• Radar Processing
• Communications Receivers
• FLIR Processing
• Secure Communications
• I/Q Signal Processing Applications

Procurement Notes

Verify the specific suffix 'TZ' against the manufacturer's current production status, as datasheets may list variants like BZ/TZ. Confirm that the Mil Level I testing requirements are met if high-reliability qualification is necessary for the application environment.

Selection Notes

Select this component when a complete dual-channel signal chain is required without external amplifiers or references. Ensure the system can accommodate the three-supply architecture (±5.0 V analog, +5.0 V digital). Verify that the parallel CMOS/TTL logic interface matches the host processor capabilities.

Part Context

Manufactured on Analog Devices’ MIL-PRF-38534 MCM line, the AD10242 integrates discrete components typically found in multi-board designs into a single monolithic unit. This integration reduces board space, minimizes parasitic effects, and improves overall system performance compared to discrete solutions.
