Replacement verdict
Not a drop-in replacement
The AD8113JSTZ and AD8110ASTZ are not drop-in replacements for one another. Although both are analog crosspoint switch ICs from Analog Devices, they differ in channel count, package footprint, and control interface, so a direct board-level substitution is not possible without redesign.

Key electrical and mechanical differences between the two devices
| Parameter | AD8113JSTZ | AD8110ASTZ | Why it matters |
|---|---|---|---|
| Matrix Size (Inputs x Outputs) | 16 x 16 | 16 x 8 | Defines the number of input channels that can be routed to output channels; a 16x16 device supports twice the output fan-out of a 16x8 device, so they are not directly substitutable in routing capacity. |
| Package / Mounting Type | 80-LQFP (surface mount) | 80-LQFP (surface mount) | Package and footprint determine board layout compatibility; both share the same 80-lead LQFP, aiding physical interchangeability. |
| Number of Outputs | 16 | 8 | Output count directly affects how many destinations can be driven simultaneously; a 16-output part cannot be replaced by an 8-output part without losing routing capability. |
| Supply Voltage (Dual) | ±5 V to ±12 V | ±5 V to ±12 V | Operating supply range must match the system rails; identical ranges mean both can operate in the same analog signal environment. |
| -3 dB Bandwidth | 60 MHz | 60 MHz | Bandwidth determines the maximum signal frequency the switch can pass with acceptable attenuation; matching bandwidth supports similar video/signal routing performance. |
| Channel-to-Channel Crosstalk | -70 dB (at 5 MHz) | -70 dB (at 5 MHz) | Crosstalk indicates signal leakage between channels; equivalent crosstalk performance means similar signal isolation in dense routing applications. |
| On Resistance (RON) | ~10 Ω | ~10 Ω | On resistance affects signal attenuation and load driving; similar RON values give comparable insertion loss behavior. |
| Operating Temperature Range | 0°C to +70°C | -40°C to +85°C | Temperature range determines suitability for commercial versus industrial environments; the wider industrial range of the AD8110ASTZ allows use in harsher conditions. |
| Control Interface | Parallel / serial digital control | Parallel / serial digital control | The control interface dictates how the host configures routing; matching interfaces simplify firmware and pin-compatible control wiring. |

Frequently asked questions
What are the key differences between the AD8113JSTZ and AD8110ASTZ?
The AD8113JSTZ is a 16 × 16 crosspoint switch, while the AD8110ASTZ is a 16 × 8 crosspoint switch. Both are analog crosspoint switches from Analog Devices, but they differ in matrix size, package, and operating temperature range. The AD8113JSTZ is supplied in a 100-lead LQFP package, whereas the AD8110ASTZ is supplied in a 80-lead LQFP package.
Are the AD8113JSTZ and AD8110ASTZ pin-compatible?
No. The AD8113JSTZ uses a 100-lead LQFP package and the AD8110ASTZ uses an 80-lead LQFP package, so they have different pin counts and land patterns and are not pin-compatible.
What are the matrix configurations of these two crosspoint switches?
The AD8113JSTZ provides a 16 × 16 switching matrix (16 inputs to 16 outputs), while the AD8110ASTZ provides a 16 × 8 switching matrix (16 inputs to 8 outputs).
What are the operating temperature ranges for the AD8113JSTZ and AD8110ASTZ?
Both devices are specified for the commercial temperature range of 0°C to +70°C, consistent with the "J" and "A" temperature grade designators in their part numbers.
Can the AD8110ASTZ be used as a drop-in replacement for the AD8113JSTZ?
No. Because the AD8110ASTZ has half the output count (16 × 8 versus 16 × 16) and a different package and pinout, it cannot serve as a drop-in replacement for the AD8113JSTZ. Any substitution requires redesign of the board layout and verification against the system's switching requirements.
Do both devices support the same control interface?
Both are digitally controlled analog crosspoint switches from the same Analog Devices product family and use a parallel control interface for channel selection. However, the exact control word width and register mapping differ because the AD8113JSTZ controls a 16 × 16 matrix and the AD8110ASTZ controls a 16 × 8 matrix; designers should consult each device's datasheet for the specific control protocol.
Which device should be selected for an application requiring 16 outputs?
The AD8113JSTZ should be selected, since it provides a full 16 × 16 matrix with 16 outputs. The AD8110ASTZ provides only 8 outputs and cannot route 16 independent output channels.
