| Preliminary Data Sheet July 2001 LSP2916 16-Channel, High-Voltage Driver Features I I I 16 amplifier channels available in one package. Outputs from 0 V to -298 V per channel. Programmable output current limit (50 A to 300 A). Fixed gain set by internal resistors. (The fixed gain for version A is -32 V/V, and -66 V/V for version B.) Minimal external components. The LSP2916 requires one negative high-voltage power supply (VHN) and one positive 5 V analog power supply (VLP). Corresponding to the 16 channels, there are 16 negative input voltage pins, -INx (x = 1, 2, . . . , 16), and the corresponding 16 output pins, OUTPUTx (x = 1, 2, . . . , 16). +IN is the noninverting input for all 16 amplifiers, which means all the amplifiers share the same noninverting input. +IN should be connected to GND for typical applications. IBIAS pin will set the current limit for the amplifiers by connecting it to an external resistor. The LSP2916 is available in a leaded surface-mount 64-pin MQFP package. I I Applications I I Optical crosspoint switches. Optical microelectromechanical systems (MEMS) components. Block Diagram LSP2916 RF Description This LSP2916 16-channel, high-voltage (HV) driver is targeted for microoptomechanical systems. Each device contains 16 high-voltage amplifiers with an output voltage range of 0 V to -298 V. Internal gainsetting resistors provide a fixed gain of -32 V/V, thereby minimizing external component count. Each amplifier can output up to 300 A, ideal for deflection and control of optical MEMS mirrors. Output current limit is programmed by an external resistor. Additionally, careful attention was paid to minimizing offset drift and gain variation over temperature. The internal block diagram is shown in Figure 1. There are two versions, version A (LSP2916A) and version B (LSP2916B). For version A, RF = 8 M and RIN = 250 k; and for version B, RF = 8.25 M and RIN = 125 k. So LSP2916A has the fixed gain of -32 V/V and LSP2916B has the fixed gain of -66 V/V. -IN1 RIN - OUTPUT 1 + RF -IN16 +IN RIN - OUTPUT 16 + 1682(F) Figure 1.

Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability. Table 3. Absolute Maximum Ratings Parameter Power Supply: VHN VLP Operating Temperature Storage Temperature Ambient Temperature Min Typ Max Unit V V C C C Application Notes LSP2916 is recommended for MEMS optical systems. It features programmable current limit while the output can swing up to -298 V. With all the feedback resistors inside the chip, there is no more need for these resistors in the external circuit. Safety Handling for the High-Voltage Device LSP2916 is designed to operate up to 298 V negative power supply, so special care should be paid to safety issues. Bypass Capacitors/Protection Series Resistor for the Power Supplies To minimize noise coupling to the output, a 0.1 F bypass capacitor should be placed as close as possible to all power supply pins. Additionally, to avoid the possible degradation of the LSP2916 when VHN is hot switched, a 10 series resistor between the VHN pin and the VHN power supply is required. 0 -160.0 -298.0 4.5 5.0 5.5 -5 25 85 -40 -- 85 -5 25 70 Handling Precautions Although protection circuitry has been designed for this device, proper precautions should be taken to avoid exposure to electrostatic discharge (ESD) during handling and mounting. Agere Systems Inc. employs a human-body model (HMB) and charged-device model (CDM) for ESD-susceptibility testing and protection design evaluation. ESD voltage thresholds are dependent on the circuit parameters used in the defined model. No industry-wide standard has been adopted for CDM. However, a standard HBM (resistance = 1500 , capacitance = 100 pF) is widely used, and therefore, can be used for comparison purposes. The HBM ESD threshold (>500 V) presented here was obtained by using these circuit parameters. 4 Agere Systems Inc.
