3PD9708(E) 8-BIT CMOS DIGITAL-TO-ANALOG CONVERTER FEATURES












125 MSPS Update Rate 8-Bit Resolution Linearity: 1/4 LSB DNL Linearity: 1/4 LSB INL Differential Current Outputs SINAD @ 5 MHz Output: 50 dB Power Dissipation: 175 mW @ 5 V to 45 mW @ 3 V Power-Down Mode: 20 mW @ 5 V On-Chip 1.10 V Reference Single +5 V or +3 V Supply Operation Packages: 28-Lead TSSOP Edge-Triggered Latches Fast Settling: 35 ns Full-Scale Settling to 0.1% APPLICATIONS



Communications Signal Reconstruction Instrumentation Video re-construction PRODUCT DESCRIPTION The 3PD9708(E) offers exceptional ac and dc performance while supporting update rates up to 125 MSPS. The 3PD9708(E)’s flexible single-supply operating range of +2.7 V to +5.5 V and low power dissipation are well suited for portable and low power applications. Its power dissipation can be further reduced to 45 mW, without a significant degradation in performance, by lowering the full-scale current output. In addition, a power-down mode reduces the standby power dissipation to approximately 20 mW. The 3PD9708(E) is manufactured on an advanced CMOS process. A segmented current source architecture is combined with a proprietary switching technique to reduce spurious components and enhance dynamic performance. Edge-triggered input latches and a temperature compensated bandgap reference have been integrated to provide a complete monolithic DAC solution. Flexible supply options support +3 V and +5 V CMOS logic families. The 3PD9708(E) is a current-output DAC with a nominal full-scale output current of 20 mA and > 100 kΏ output impedance. Differential current outputs are provided to support single-ended or differential applications. The current outputs may be directly tied to an output resistor to provide two complementary, single-ended voltage outputs. The output voltage compliance range is 1.25 V. The 3PD9708(E) contains a 1.1 V on-chip reference and reference control amplifier, which allows the full-scale output current to be simply set by a single resistor. The 3PD9708(E) can be driven by a variety of external reference voltages. The 3PD9708(E)’s full-scale current can be adjusted over a 2 mA to 20 mA range without any degradation in dynamic performance. Thus, the 3PD9708(E) may operate at reduced power levels or be adjusted over a 20 dB range to provide additional gain ranging capabilities. The 3PD9708(E) is available in 28-lead TSSOP package. It is specified for operation over the industrial temperature range. PRODUCT HIGHLIGHTS




Manufactured on a CMOS process, the 3PD9708(E) uses a proprietary switching technique that enhances dynamic performance well beyond 8- and 10-bit video DACs. On-chip, edge-triggered input CMOS latches readily interface to +3 V and +5 V CMOS logic families. The 3PD9708(E) can support update rates up to 125 MSPS. A flexible single-supply operating range of +2.7 V to +5.5 V and a wide full-scale current adjustment span of 2 mA to 20 mA allows the 3PD9708(E) to operate at reduced power levels (i.e., 45 mW) without any degradation in dynamic performance. A temperature compensated, 1.10 V bandgap reference is included on-chip providing a complete DAC solution. An external reference may be used. The current output(s) of the 3PD9708(E) can easily be configured for various single-ended or differential applications.
